Pressurization not working properly

Same here but on a hosted server (my own).

I realized that this only happens when i dock a large grid ship onto another large grid ship (with landing gears so far, haven´t tested the alternatives).

After doing so, both ships get depressurized and cannot be repressurized until i restart my server.

Docking small grid ships on a large grid ship is fine, no issues here. Docking large grids with stations - haven´t tested it yet.

This pretty much breaks the game for me for this issue occurs quite frequently on my server.

Have to restart it every time - not a suitable solution on a MP Server...

I still don´t know what may be the cause, landed ships of every size and sometimes it happens, sometimes it doesn´t.

Anyone yet know how to reproduce it ?

Yep same here.

We built a large grid ship and when another player enters it or lands a ship we don´t have any pressure on the whole ship.

Same here on a multiplayer server.

Everything works fine unless at last one person is close to the pressurized grid.

After all users leaving the grid and re-enter the grid again the lights on the air vent shines yellow.

After a while, the room is pressurized again. I don´t know what it triggers.

Maybe an initialisation problem.

Since another month is gone now and no solutions to be found:

When can we expect more to this issue ? Any information if this will get fixed during the next year ?

Sorry to ask again but this issue just makes it impossible to play on ANY Server for me and some friends.

Had to edit my comment because of some issue with Chrome Browser (works with IE).

I started experiencing problems with pressurization today. Rooms depressurized and at first the vents showed "Not Pressurized". I quit out of game and loaded it again. Vents start to pressurize, but they do not keep at 100%. I did an experiment where I blocked myself in a 1x1x1 room with vent; I could pressurize to 100%, but if I turn off vent, pressure drops. The larger the room, the faster the pressure drops. All blocks in ship have 100% integrity.

After several switching the airlock of the base with pressurization bug,sometimes it fixed but airvent uses tons of oxygen for pressurizing the area.

Noticed this bug on my station's hangar, pressurizes fine sometimes but can get stuck yellow. Occasionally removing a block then putting it back un-sticks it and it can be pressurized again though sometimes that fix makes it take a lot of air (and time) to pressurize and depressurize. Restarting the server fixes it and everything works like it should.

Just came across the same issue. Also can reproduce this relyable in my current save.

Restarting the game fixes this ... for simply a single other interaction

Hi guys, thank you very much for your feedback.

X39: Please, can you provide the save with info how to reproduce the issue? It would be very helpful for investigating the issue.

Thanks again and have a nice day :)

I have this issue and tried multiple ways to work my way around it. What (kind of) seems to work is to use a separate system for O2 production and air vents that is completely disconnected from the normal conveyor system used for items/ores/materials etc.

O2 pressure will still be lost randomly when exiting/entering buildings and rooms or when removing/placing blocks but with a separate system the air will be replenished immediately whereas with a combined system I would get one green light on the air vents but they would not replenish the air lost.

Another thing that happens when the air vents get stuck is that my O2/H2 generators will start running at full power but will not produce anything, even if I'm sitting in a cockpit. Restarting the generators will sometimes fix this but not always. Recycling base power does not seem to have any effect.

Could have sworn i pressed post ...

Steps to Reproduce:

1. Walk through the closed Door to your right, wait until other door opens
2. Walk through now open door into the "hangar area" until the door closes behind you
3. Repeat the steps 1 - 2 into the opposite direction
4. Move to the buttons panel and press "1" to open the hangar doors
5. Repeat Step 1 - 3, notice that no air vent in the current grid is working anymore (Yellow light)

Note that this world uses a very basic script for the detection of direction (to properly pressurize or unpressurize).

Hello - again nothing new here ? This pressurization bug is the reason i quit the game for MONTHS now - still no fix ?

What information do you need ? How can we help ??

I see this issue quite often, especially in servers. Some air vents suddenly show not pressurized even though the room is sealed. Sometimes opening and closing the doors fixes the issue, but not all the time.

I've also seen this in my single player game when working on airlock script. In it I added a "decontamination" option which basically opens all the doors for 60 seconds to vent all the air to space. This feature seems to often break several vents randomly with this "not pressurized" issue, especially when doing this "decontamination" several times in the row. Restarting the game fixes the issue.

So just now occured again this morning at 08:38:

Having a small area fully pressurized, opened a door to space - boom pressurization level down to zero. Now closed the door again and the vents still show "Yellow" - air not coming back.

The room still is completely sealed.

The thing is, now if i open a door to an attached room (also fully pressurized), the air of this area also gets sucked out to the first area, making this new area also "yellow" on all vents. Same with the next attached one and so forth.

Just like the disease spreads from one room to the next :)

Oh and just to be sure: This happens in a vanilla world as well as in a modded world.

Got the log file and the world itself to dropbox: https://www.dropbox.com/sh/y23faxbk5lr9ozi/AAAREQMQlzpY9mcdcfEEyctZa?dl=0" rel="nofollow" target="_blank">https://www.dropbox.com/sh/y23faxbk5lr9ozi/AAAREQMQlzpY9mcdcfEEyctZa?dl=0">https://www.dropbox.com/sh/y23faxbk5lr9ozi/AAAREQMQlzpY9mcdcfEEyctZa?dl=0

If you need anything else feel free to contact me.

I ran into this same problem on a dedicated server. My ship was originally built airtight and pressurized fine. It had 2 separate compartments with their own air vents. The upper compartment was fine for several days -- it even re-pressurized correctly after I derped and opened both airlock doors at once.

Eventually i went into the lower compartment to check something, and when I opened the door, the entire ship de-pressurized. After closing the door between upper and lower compartments, i was able to re-pressurize the lower compartment, but the upper compartment remained bugged for many days afterwards. I logged in and out many times and the server was res restarted on a regular schedule every 6 hours. Yet the problem persisted until I stopped playing on the server.

Frustration would be less a thing if someone actually would respond to this issue. I don´t think only so few ppl have problems here - get ppl to vote here !

Happening again and again, Keen what more information do you need ? Please advise

I had to restart a map on my dedicated server because this was happening, out of nowhere(from my perspective) rooms that were previously pressurized suddenly weren't anymore. Same issue as reported, on a restart they were ok, but when I would use a door or let it otherwise become unpressurized, it wouldn't recognize the room as a whole. Even newly constructed rooms that were just a closed block out of armor(Full square) and all the necessary stuff inside of it didn't want to pressurize anymore.

We have been having the same issue on our private MP server. Server restart fixes the issue as does copying the grid and pasting it back into the world, or pasting it into a creative single player game... very annoying.

Hello there.

The same bug occurred multiple times while I was playing on a multiplayer server.

We encountered this problem as we tried to pressurize a base on an asteroid. Of course, we triple-checked the air tightness of the whole building before considering this anomaly as a bug. But the fact is that restarting our server solved the problem... at least temporarily. Since then, our base regularly lose its air tightness - often when we interact with doors (which are obviously between fully pressurized rooms).

It is quite a game-breaking bug, since we must frequently restart the server in order to properly play on it. Unfortunately, it is difficult to provide information that weren't already mentioned above.

Please consider to investigate further this bug (if that's not the case yet). Your game is really fantastic, but would be even better without this kind of problem. Keep it up !

Best regards,

A fellow Engineer

EDIT : I forgot to mention the fact that sometimes a room or another stay pressurized when the others are stuck in a bug state, even if its doors are open.

Hello again,

I'm actually on the same multiplayer server than Draco Nocte (the one who posted above me) so my post will not give you any further explication of the observation we could have about this bug. Apart for the fact giving more visibility to this post.

I just came to convey to you all my gratefulness about this game, I discovered it by a friend's recommandation weeks ago and i'm getting closer to the 200hours now, just fell in love with this game.

One more time, i invite you to investigate on the bug, if it's not already in process of course, and I hope that this is gonna be fix soon we will be able to fully enjoy the game again.

Warmly,

A noob engineer who prayed Klang this morning.

I am beating a dead horse on this topic but I too have a pressure problem. Built a space base. Found and closed all air leaks. Built air vents for two sections (inner hub and outer ring). Pressurized both areas and maintained pressure for the last week. I installed sensors on all sliding doors to automatically open and close. Pressure still working. Today, pressure failed. I have added no interior pressurized space. I have 8 oxygen tanks at 100%. I have 8 oxygen farms and 5 O2/H2 generators with plenty of ice to spare. Can't figure out why they stopped working in two separate pressurized zones. I have now closed the game and restarted it while I am typing this. After the restart neither area will pressurize with all 15 air vents showing one yellow light so the problem persists. Another related issue that I have noticed is that the Medical Room and Survival kits will not supply oxygen either. They are not co-located and reside in each section. I can go to a docked ship and get oxygen replenished from the onboard survival kit.

It appears that O2 is not passing through the conveyors. I did get O2 from a Cyro chamber when I entered it.

Same issue here, my brother and I have spent the past few *weeks* trying to figure out the cause of this bug even going so far to play without any mods (which we hate to do) and frankly we are reaching our breaking point in patience as it seems nothing has been done to *fix* this bug.

There is a thread about it on reddit and also one on steam about the problem; I really do wish a solution could be found since it makes the game unplayable after awhile (and having to constantly restart the server is not a solution)

Yep. All this. I've got a station, multiple floors connected by an elevator. Leak detector shows no leaks. 100% oxy tanks x4, vents right on top of those 4 tanks. That room won't pressurise, neither will the crew quarters (individual or common) on the floor above. Yesterday, pressurised. Tonight, not pressurised. Very aggravating/confusing. Last time, a sacrifice to Clang fixed the problem... that trick not working tonight.

I've also had it seem like the o2 gen isn't working, walked away and come back to find it 'suddenly' working again, untouched.

Im going to leave a comment here as well. This is still very much and issue. And makes playing survival MP an absolute pain.

Private host with brothers. our ship is perfectly air tight with self closing airlocks. hours will go by and randomly, entire floors will become depressurized with no oxygen.

the ONLY will to fix it is to reload the world, and the ship instantly gets all its air back.

Ill share a world if need be, but im not sure how that helps or matters since this seems to be such a common issue.

I have this problem too, at the beginning I destroyed the rooms inventing many theories to try to work.

Basically, when it occurs, it appears to be general or in an intermediary region.

I used a plugin that displays where the leaks are and shows nothing.

I'm also having a similar issue. Built a large launch silo underground. Just been layering rooms around the central chamber. Drilled out an entire floor and sealed it up airtight then pressurised it. Just separated that floor into 4 rooms using doors and built a med bay. Added all the cosmetics and everything. Built a medical room for healing/respawning, then depressurised the room so I could put a hole in the ceiling without wasting the oxygen, and connect the medical room to conveyor system for H2/O2 replenishment. Repressurized the room and the vent just kept pumping without increasing the pressurization %. Turned the vent off then back on and now the entire floor, including all the other isolated rooms are claiming they aren't pressurized even though I didn't make any changes to their armor blocks. Tried reloading and reconnecting the system but I just can't seem to fix the bug.

Still an issue.

Got a large hangar with 9 air vents connected to oxygen tanks and the rest of the conveyor system.

Got timer blocks setup so the room gets depressurized first and then opens the hangar door. Works fine.

But when I do the reverse, sometimes the air vents will put pressure in the hangar and it takes about 15 seconds to fill. Sometimes it takes ages to fill (1 minute and just 0,3 pressure on the room). And sometimes the air vents say there is a leak and do nothing.

It's basicly ransom, everything is sealed because sometimes it does work.

I'm on a self hosted dedicated server with 2 persons. Using quite a lot of mods, but guessing the same issue is without mods?

Restarting the server works.

I'm getting this from time to time on single player. Sometimes the airtightness spontaneously fails while I'm sat in a chair or walking in the cabin. Sometimes it fails briefly, sometimes it fails until a reload.

Got this issue with my large grid ship. On MP dedicated server (I'm not the admin), both in space and on planets, with and without mods.

The ship is sectioned into small, medium and large compartments. Smallest has an internal volume of around 328 cubic metres, while the largest has a volume of 4125 cubic meters.

All sections pressurize with little trouble, however, frequently when opening a gate (frostbite), or sliding door the pressure will go negative, somewhere around -9000. This has caused my 3 o2 tanks to completely empty trying to re-fill the volume, but usually the system just bugs and shows no lights on the vents.

Closing the gate / door does not restore airtight status.

Re-opening the gate / door, sometimes zeros out the pressure again, but except for rare occasions, a server restart is required to fix the 'leaks'.

I also noticed that the area immediately around my ship, on the outside shows high oxygen, so it seems the air tight calculations are reading an area extending to the outside of the ship - also explaining why refilling a hangar after restoring air-tightness can use up all my o2. I've confirmed this with an exterior vent - which when set to depressurize shows exactly the same pressure as the previously bugged hangar vent. Having the hangar set to pressurize, and the exterior vent set to depressurize seems to just cycle the same volume of air through the system, neither gaining any ground. Again confirming that the airtight volume extends beyond the ship bulkheads.

The hangars use only vanilla blocks, no weird angles, and have no gaps. Blocks used:

Light armor blocks, light armor half blocks, sloped windows (not an issue as the volume behind the windows remains airtight unless deliberately vented), sliding door, gate, piston (in floor but capped off on all exterior sides), welders (in floor but capped on exterior side).

I can reproduce this issue by opening an exterior door, and occasionally by attempting to depressurize a space. Adding blocks to the hull occasionally causes the bug too.

This happens with and without o2 / vent management scripts.

Edit: I can't reproduce this in offline mode. Seems to be a MP bug.

Still no reaction from ksh here ?

What Information do they need ? Is this report getting ignored still after over 1 year ? How can we help ?

Randomly happens no real reproducible steps that I have found. I play on MP. Only fix is to restart the server.

I am having this problem with an underground base on the earthlike planet. Sealed rooms with air vents will randomly have the vent indicators go black and the room will be depressurized when I go through the door. Next time I go through the space it will be pressurized. I thought maybe it was due to the weather feature being turned on, but turning off weather effects didn't fix the issue. This needs to be fixed!

Disabling Oxygen and Air tightness, saving, re-nabling Oxygen and Air tightness seems to fix the issue, but it DOES need to be fixed. And it doesn't always happen to worlds. Some get it, others don't, and even if it DOES happen in a world, it may affect one grid, it may affect more....it's a literal dice roll whether or not it occurs. And they want more information. On something that you can't predict WHEN or IF it'll happen. I mean, I know they need steps to reproduce it, but with something like this, there ARE no steps to reproduce it. It just...HAPPENS, like it''s on some random number generator.

I have the same problem, from time to time, I cannot pressurize my airlock but my base still has oxygen, when I open the door the problem spreads and I start to lose oxygen in every room I enter without being able to recover it. I think this is because I built a very large base for my computer, I have a ship near my base that can still pressurize without problems when this happens.

Restarting the server solves the problem, once it corrected itself and crashed again minutes later.

My computer is:

AMD athlon II x 3450

6 GB of RAM

Nvidia Gt610 2G gddr3 graphics

Windows 7

A related problem, when I depressurize a room it does not always remain at 0%, sometimes it remains at 0. (decimal) E-8,

I'm running into this issue currently while hosting a MP server with 1 other person playing with me. My entire ship is air tight and Notice that I will loose room pressure from 100% to 1-2%, sometimes I would loose pressure completely. Other times I will watch pressure slowly climb from 1% to roughly 75%. this would take 30 minutes or so during the time frame (regardless of room size or a large amount of vents in the room). While the pressure climbs it will drop .5% every couple seconds. This happens to all of my rooms on the ship all at once big and small. My experience with this was on the large grid ship.

Same - we're running a 1.197.069 dedicated server. We've just turned off all air vents. It kept bleeding oxygen out of the entire base. Periodically I would return to an airtight room to find that the entire room had depressurized and was using more O2 to re-pressurize - even though no blocks had changed in the room, and no doors had been opened/closed.

We've also had rare instances where a room would go to -500 or 600% pressure and never pressurize even though it was sealed and air vents were feeding O2 in.

This hit me 2 days ago, 2 diff worlds on 2 diff saves. Fully airtight, full power, ice, etc. 2 vents and 2 h20 genies and still have room not pressurized. Smh

Same problem rooms will not presureize but I have had times when walking back and forth through a doorway triggered it to pressurize again.

At one time before launch I had hanagar doors open and close and instead of pressurizeing it went -56,000 while I walked back and forth through the regular doors and open/closing hangar doors trying to figure out what was going on.

Got everything green and got rid of the negative pressure but now today it is all yellow again and will not pressurize for some reason and nothing has changed.

Some friends and I are having the same issue on our server. Had part of our base pressurized. Just a few small rooms with a "dumb" air lock to the non pressurized area. (I say "dumb" because it's not one that has a depressurize vent to save o2)

At any rate everything worked fine for a while and then all of a sudden it gave us the yellow light out of nowhere. We've searched around and can't find any leaks, nothing has changed from before. We have plenty of Ice and the o2 tanks are full.

Our vents are connected to other objects like Med Stations and Cryo tubes. Do the vents need to be on their own independent connection? Has anyone experienced this issue who had that set up?

Side note:

I just thought about putting in a sorting conveyor set to force pull oxygen to the vent, I wonder if this would solve the issue. Will test and get back.

TESTED: FAILED

The conveyor sorter block does not work with oxygen at all

It will often fail on all oxygen systems on the server, whether they're connected or not. It's like a memory leak or memory buffer problem - once it uses the data allowance up for keeping track of the oxygen systems, it just turns off. Doesn't seem to affect cockpits, more just pressurised rooms.

This post needs more votes.

Same bug, at this point the sever has to be reset every time someone leaves their ship to go mining. Get back and the vents seem to be endlessly 'sucking' when I get back even when the hangar is depressurised when I left.

But wait it gets better, when I then leave the hangar depressurised because even though I have sealed all bulkheads and doors the best I can do is it be yellow light, when I enter any pressurised areas of the ship the instantly 'bug out' and vent too, the only fix is to respawn the ship or base and or restart the whole server which is not tenable. It hurts because it's such a simple issue that is rendering the game nearly unplayable for me.

The trigger action seems to be using my connectors. When I return and drop my ore off via any connector (ship sealed and pressurised or not) it bugs out.

Hello All!
I've been having a look through this thread and have tested X39's save from quite some time ago. For me, it is working as intended and although goes to yellow, then starts pressurizing as expected straight after closing the door and to green. Is it possible that some other people could supply some saves where this is happening? Also, please include reliable steps for reproducing the bug as it's really helpful!

This is not a world issue. This simply happens after the game has been running for some time, same as the 'your graphics card may have overheated error'.

As such, keen should not be denying they don't have enough data when it's clearly some kind of memory issue. This happens in single player offline also. It happens more frequently when the world is big and the game has been running for some time (hence why people see it more in MP servers).

Stop labelling issues with 'need more information'. You are the developers and this issue should be clear to you.

It's becoming a tiresome sight on this support portal with the 'need more information' excuse put about everywhere.

Bigger rooms to be sure. I've not had it happen in small block rooms, only large. Also, never in cockpits or anything that you sit in.

hi there,

i believe i just found a way too 100% replicate the issue!

i have a back-up from our dedicated server that i can send you, but it is about 60 MB so i can't attach it to this message. I'd be happy to give you this back-up so your dev can look it up.

in this, you'll find a large grid ship named ''ATL-A'' ( a big red/black mobile base/factory ship)

This ship has a vast interior zone which is normally pressurized without any problems. in the back of the ship there is an airlock leading to an unpressurized hangar which is sealed from the outside by a hangar door.

as soon as anyone open/close the hangar door, the ships Air vents shows a ''not presurized'' status. Once that happens, there's is no way to presurized the ship back. the only way to re-presurize the ship is to re-start the server. on logon, it will work perfectly as long as we do not use the hangar doors. using conventional ''dumb'' airlock causes no issues.

i have successfully replicated the situation mentioned above 3 times today.

we tried finding air leaks using the ''buildinfos mod'' but the mod says there are none but it won't presurize

except ''Buildinfo'' (which we installed at our second occurance of the problems) we run completely vanilla on a GTX gaming serer (the hosting service you recomand on your website)

I'd be glad to provide what ever help i can to help resolve that frustrating issue.

I think I have found a way to replicate this problem.

1º Build a large hangar with pressurized hangar doors

2º Pressurize, (making sure you have enough space to store the oxygen again and something else)

3º Depressurize and wait for it to finish

4º Open the hangar doors

5º Go mining for a while (I'm not sure it's necessary)

6º Close the doors

7º Try to pressurize again.

You should already have the problem with the pressurization, "yellow lights"

Sometimes the problem begins at the 3rd point depressurizing much more than 0% reaching negative numbers.

I have tested this with small hangars and it works perfectly so the size must affect, maybe if you test it on a NASA computer you will have to create a hangar many times bigger for the problem to occur.

Another thing, try to build Space Engineers from https://github.com/KeenSoftwareHouse/SpaceEngineers code but it fails. Is it still possible? What else do I need to install that is not in the instructions?

I do not put the world because it will happen in any game you create.

Hello,

After a (very) long time saving and reloading, i also discovered a way to replicate the issue. This is working 100% of the time on my computer. Here is the procedure :

- Minimal large grid version... : https://steamcommunity.com/sharedfiles/filedetails/?id=2471812037

- ...with a bunch of light armor on it : https://steamcommunity.com/sharedfiles/filedetails/?id=2471814666

- Create a new world, creative mode. Go to Mars Base or Moon Base (couldn't replicate in space). Enable experimental mode and ingame scripts. If you don't want to, then you'll have to trigger the bug manually.

- Get outside

- Spawn the "TOWER" version with all the light armor on the top (try to attach the small base to the ground).

- Make sure the door is closed and push button 1 on the command panel.

- The programming block will start opening the door, waiting 3 ticks, closing the door, waiting 3 ticks, and so on.

- After a while (sometimes seconds, sometimes 2 minutes, shouldn't be too long), you will see the outside vent trying to pressurize the outside environment.

If that does not trigger the bug on your side, stop the program using button 2, close the door if needed, then add more blocks to the grid. I mean, really, could be a lot more depending on your computer. Eventually, restart the program using button 1. You can also try to enable your jetpack and go back and forth.

Further notes :

- Once the bug is triggered, returning to the main menu and reloading will make it go away (until next time).

- Also, the vents will enter into some weird state. Sometimes they will have very low pressurization speeds (like 0.01 % every second), but still working. Another time, they will just stay yellow, without pressurizing the room. I even got some negative pressure states toying with this grid.

- I said "waiting 3 ticks" earlier, about the door, but that's probably not correct. With an actual grid (not just a bunch of steel, because investigating this bug all started with my base...), i had to increase that value, up to ~10-12 to trigger the bug.

- This also means that if you don't wan't to enable the experimental mode, you'll have to open the door, wait 3 ticks (yeah...), and close the door. And probably do that multiple times to have a chance to catch it. On an actual grid, since that value can be larger, you have more chances. It's quite easy to trigger it manually on my actual base.

Please find some screenshots below, the script used in the programming block, and also a brand new save where i replicated this. Hope this will help, since this bug is really game-breaking in survival.

Screenshots attached :

1 - The "minimal" thing

2 - The inside, just a vent

3 - The "minimal" thing with a bunch of light armor...

4 - ...pressurizing the moon after pushing button 1

5 - Pressure of the outside vent.

6 - Pressure of the inside vent, going up 0.01% by 0.01%.

7 - Final view

bonus - Large negative pressure on another similar grid

We can replicate this issue most of the time. Usually happens when we connect two ships with a merge block. The ships will not pressurize while merged. When disconnected they will usually start to pressurize again. In some cases, we need to restart the server to get it working again.

I have another case of reproductible pressurization bug.

It requires two doors (similar to a rudimentary airlock) but works in space and on a fairly small structure with no CPU load to speak of.

You can spawn the attached blueprint anywhere (in space or on an asteroid) in a new custom/empty world game in creative mode. Hitting the "Run" button from the programmable block will toggle the test program on and off (as indicated by the red light).

Looking at the air vent through the window, you should see the indicators shortly turn into a single yellow light.

If you toggle the program off at this point, you can either see the room re-pressurizing after about one second, *or* witness one of these strange results:

- the room re-pressurizing very slowly (more than 10 times slower than usual)

- the vent staying stuck indefinitely on a yellow light (reported as "can't pressurize" when inspected from a terminal)

Running the program again usually gets the vent unstuck. If you recompile the program, you'll have to hit 'run' once to start it.

I ran into this bug while trying to come up with an automated airlock system. I had an initial recognition phase where each door was tested to see if it opened to a pressurized or unpressurized space. That would work fine for a single airlock, but mess up the pressurization completely when two airlocks in the same room were tested in parallel. I finally managed to get it working, but I had to enforce a minimal delay of 10 ticks between any two doors closing or opening.

If you like, I can post a saved game with the working system and another showing how removing this delay wreaks havoc on the air vents. On the other hand, the code is about 500 lines long, using a kind of rudimentary, undocumented homemade multitasking scheduler and might be a tad bit hard to read.

Just bumping this. New Nexia server, same issue. A long ship, some parts pressurized some are not. Keen, this is a huge issue.

Created by connecting a large ship to an NPC base. Rooms at the front of the ship were pressurized, but the particles always came from the vent. Most of the ship did not pressurize.

Some things we have tried:

Of course not having ice can be a problem. You will see one green light on your vents.

Filled h2/o2 gens with ice. Solved.

Next, if you have a room or a large ship with airlocks. Some vents on pressure some on de-pressure. Maybe a block is missing.

Switch all vents to pressurize. No joy.

Room identification reset. Remove a block and put a block back. Still did not work.

Final ridiculous resolve.

Cut the ship with creative tools on.

Started an empty world game, same mods, and creative.

Pasted the ship and waited for it to repressurize.

Solved.

So if you play on NewNexia server and have this issue I will be happy to reset your ship for you. I do not see this getting fixed.

I have the same bug. I also noticed that the Medical Room will stop dispensing O² and H² if it is in an area affected by the bug.

I've been having this issue for a while, and I think I finally narrowed it down a bit.

Doors closed manually very rarely have the issue for me, if at all. It happens only when a door is triggered via a script or Timer Block, and it can even effect doors that are not directly triggered.

Let me give context to my experience:

I've got an airlock (two Gate blocks and a vent) connected to a hangar on my asteroid base, and timer blocks to control them. I have two sets of timers, one to pressurize, and one to depressurize, for each the airlock and the hangar. Oftentimes, when triggering one of the timers, one of the airlock Gate blocks will not seal, or one of the hangar Blast Doors will unseal, even if that door was not directly triggered. The timer blocks are on a small rotor subgrid to save on space, and that seems to increase the likelihood. When using the leak finder in BuildInfo, it can't find the leak because the doors are closed, but somehow it's still losing air, and the particle effects on the vents when they try to pressurize the unsealed room are pulled in the direction of the leaking door if it's nearby.

I then played around a bit in a test world without mods, and found the issue still occurred, mostly with timers, but also occasionally on doors controlled with scripts.

So I think what's happening is parts of the game engine aren't double-checking a seal after that seal is triggered by another block, and it's causing a bit of miscommunication.

I've attached a 7zip of my main save file where I was having the worst issue. Mods aren't necessary for anyone else to test this because no mod blocks were used in the problem areas themselves. Simply play around with the Pressurize and Depressurize Airlock buttons, and the Open/Close Hangar buttons located on their respective panels, and you should run into the issue after one or two cycles.

it's been 2 years on this post and still nothing, this has been an ongoing issue for far longer. Can we get a fix already.

Update: the pressurization system is now totally broken in my game. I can't get it to pressurize even a small room 99% of the time. Either it won't pull Oxygen from the tanks at all, or it just spills out through closed doors, sometimes getting sucked into an adjacent room that's set to Depressurize. When it does fill, it fills extremely slowly, literally less than 1% per second, even in small or moderately-sized rooms with plenty of vents to feed them.

Sometimes it'll even get confused and start filling a room that's open to space, usually when I remove a block or otherwise upset the terrain. This usually only lasts a few seconds, then I get that static-y lag spike (see video) and it realizes there's a hole.

Here's a video of the vents not working and getting pulled through closed doors. Note the static and lag spikes when I close the (blue) airlock door:

It's clear now that what's happening is the pressurization system is getting overloaded, even with medium-sized bases. I tested multiple doors again with the new Warfare 2 ones, and it seems at first like certain door types increase or decrease chances of it happening, but over longer periods of time, this is disproven. All doors experience the issue; changing them out merely forces the game to re-check the area and make it work temporarily.

Thankfully, it seems to be a per-grid problem, as I don't have too much trouble with my ships, small or large grid. I've had some issues with my small grid ship once or twice while I was inside a pressurized hangar, but that's about it.

Until they fix it, the best permanent solution from across my various saves would be to use smaller, separate facilities instead of larger single-grid bases. You can have them connected via connectors and such to transfer power and materials, just as long as they're separate grids, you should be able to avoid this problem.

I've attached my latest offline save. I'm curious to see how different hardware impacts the chances of this happening; I'm using an i5-11600k and a 1660ti.

Oxygen farms also currently don't output oxygen to tanks, I had them on rotors before but moved all of them to my main station to check if its just the rotors but its simply not pushing any O2. I have like 16 farms made so I should see a good amount in the 2 oxygen tanks, and they are all connected to the grind, directly on conveyor pipes so this is not the issue, all of them are fully built so again its not a damaged pipe.

Right now Ice is the only way to fill them up which is really frustrating.

Aside from that rooms bug out, and need the game to restart or be stopped and rebooted.

When the game reboots anyone in a cryo-pod will instantly die, this is on both multiplayer and co-op.

So items get lost, and I checked wiki and this is NOT designed to happen.

Also May I complain about how the bug report system here has higher priority over posts that have more upvotes, its counter intuitive when newer issues are always at the back of the list where you have to search people don't want to scroll though all the bug reports to find new issues, if you could sort them to newest by default then have a option for the devs to see most voted instead of the current way I think it would be more productive for the community.

Personally I don't report stuff on new threads because its always at the back of the list where no one ever goes so I know its not going to get fixed if I report it, or at least the likely hood of it ever getting done in a timely matter is unlikely.

Anyhow I noticed those two issues regarding the oxygen system so I though I would throw it out there.

Its really not hard to test it, my provider is latterly the same provider the official servers use, so its not like they players on there would not have the same issues.

I have this issue with a Large Grid Cargo Ship I'm building. It has Airlocks controlled by Timers that are on a small grid Rotor Head. It almost exclusively uses the new Frostbite Gates, with the exception of 2 Full Hatches. 2 of its engine banks can unmerge from the ship and be used as Tug Boats. These have Airtight passageways to them that break at some 2x1 tips and explosively decompress when they unmerge. The Bug occurs when I board a Tug Boat and Un-merge it, fly around a bit, and then land and re-merge. The Vents are haywire... yellow in sealed rooms, sometimes at 1 bar and pressurizing but mostly just yellow. I will test further and provide a save if I find it reliable to reproduce.
