Ship rubber bands back to ground/connector

Hello Matthew,

thank you for your feedback. Our team will take a look at it.

I've noticed this issue 3 or 4 times since the update was released. I've seen other players struggling with it as well. It's pretty frustrating.

What I seem to have noticed is that this happens when you turn off the thrusters while connected. On my personal DS I had the same problem again, when I restarted the server it was back to normal. Ever since then I don't turn the thrusters off when docking, I just turn dampners off, the bug hasn't happened to that ship yet using this parking method.

Hello, I have not been able to reproduce this. Has this happened to you after the hotfix landed on live servers?

Can you reproduce it now? Do you have any mods installed and if yes, does it happen to you without them?

Thank you for your cooperation :)

I did just have it happen. A small grid atmo mining ship. Connected to a static grid via a connector then turned off the thrusters to conserve power. When I returned to the ship powered on the thrusters unlocked the connector. It's a bit different than the video, it is stuck to the top of the static grid instead of the connector itself. But no matter how hard I try the ship snaps back to the same place on the grid.

As I was writing this it went back to normal on it's own. I have no idea what's going on :P

Same problem here - 2 different cases on the same dedicated server

1st was just as the OP described. mining ship on the planet would not disconnect from its connector until I ground off BOTH connectors. Its been fine ever since.

2nd was in space (yesterday July 25). but This time I was returning from mining and the connectors would not turn yellow. When I exit my ship to take a closer look, the ship 'jumps' forward and there is 2 blocks of space between the connectors. When I re-enter the ship, it 'jumps' back to show the connectors face to face. Grinding off and rebuilding both connectors did not help.

I tried building merge blocks on my ship and on my station, but I had the same "Jump forward 2 blocks" problem. Eventually I used a 2nd ship to gently push my mining ship into the merge block and it merged with my station.

I had rubber banding on a ship I built as well, it kept being dragged back and I could not fly. After grinding off the landing gear all was fine, but after welding new gear and landing, it later happened again.

I have removed the vanilla landing gear and am now using rectractable landing gear mod without rubber banding issue.

Hello,

We still weren't able to reproduce the issue. Any additional information would be very much appreciated. Does anyone has a world where it keeps happen and would be willing to share it?

Thank you for all replies so far, we will keep looking at the issue.

im still playing on the same server and the problem hasnt happened in the past 2 weeks of play. It sounds like something else fixed it.

Other workarounds include cutting/repasting the grid if you're an admin, or having another player take control of the grid. It's a desync issue because you can fly off the connector to the end of your rope, and lock your landing gear and the ship will jump back to the connector locked to platform.

got this issue on de6 after removing my atmos thrusters and built ions, when trying to fly after it just drags the ship towards connector even when connectors, landing gears was off, after large ions ws mounted i was able to fly away at the speed of 3m/s but not able to stop the ship. just drifted with everything on. just deleted ship and rebuilt a new one

I had this 2 days ago on Keen NA1 server.

I was on the server for 2 weeks, finally built a miner and used a connecter, as soon as I locked it for the first time, it completely broke and never worked again properly.

I had this bug regularly forever ago... first time I've seen it crop up in a long time though. I was on a DS the night before last and after building the small grid (a welder ship) by hand and connecting it to a connector to transfer components, I was unable to pull away from the connector even though I made it out of the suction range, after that... the grid was completely tethered to its spot until the server restarted. Since it's the first time I've seen this bug in a long time I have no reliable way to reproduce it.

i am having this problem on a server to an it seem to do it when i build a reactor or connect to a connector

To reproduce it, build a ship from a BP projection that has batteries on recharge. Upon completion. Do not grind it free. Get into the cockpit and set up some groups and drag some in the hot bar. Now get out and grind the ship free. Insta stuck.

To prevent it, grind the connection as soon as building complete without getting in the cockpit or touching any control panels. Although this bug isn't exactly with connector the behaviours is exactly the same as the video.

To get the ship stuck to the connector after construction, have the connector of the BP line up with station connector, upon grinding, you will be stuck.

I have had this happened at least 4 times, twice the admin took my ship and flew it outside streaming range and fixed it. The other times I waited for server restarts.

Hello All, KSH

this the same issue as following threads:

https://support.keenswh.com/spaceengineers/general/topic/1-187-089-ship-stuck-in-space-as-if-connected

https://support.keenswh.com/spaceengineers/general/topic/ship-that-is-built-and-cut-away-from-another-connector-parked-ship-is-unable-to-move

I've had this issue a few times as well.

Some troubleshooting of my own:

- I tried griding and rewelding the connectors, this didnt work. I powered down the ship and started back up, this didnt work either. I did notice even though the ship was powered down, the blue glow was still coming out of the exhausts of the ion thrusters. I figured the ion thrusters were bugged. The ship also had Hydrogen thrusters, so after putting in some ice, i was able to move the ship with the hydrogen engines regardless of the ion thrusters being turned on or off. After grinding off all ion thrusters and welding new ones, the ship was moving again with ion thrusters.

As I wrote above, the ion thrusters were glowing despite everything being powered down, so my guess is that there is a desync between client/server regarding the status of the ion thrusters. The client thinks the ship can move with the ion thrusters, the server corrects your location since on the server side, the thrusters arent doing anything. The server syncs your client with how you are on the server, causing the rubber banding. (just like it does with high ping).

- Can other players also add hydrogen thrusters to their ship should they run into this issue and confirm my findings above?

- @ Keen: is it possible that this rubber banding of the ship is a result of more than one bug? Since it syncs the client back with what the server has calculated. And if so, do you have a fix for this or a dev tool that can identify what exactly is causing the client / server mismatch in information?

thanks.

This is usually because (in my experience on the NA servers) the SERVER does not recognize what the client is doing. Try cycling your engines, and messing with MAIN cockpit settings. This usually resolves the issue. I noticed this when I asked a faction member if my engines appeared on and indeed they were not, even though on my screen they were.

We tried to help a player on AU3 that was experiencing this. He asked for help on chat.

-The bugged ship was a small ship. We were on the earth-like planet.

-It had enough power and enough atmo thrusters on all sides

-we tried everything ie. Cycling ship's power, turning the bugged connector on and off AND grinding the connector and rebuilding it. The small ship was still attracted to the connector on his base (we tried turning that on/off/grinding that down as well).

-I even used the miner we brought to his base to lift his little small ship off the ground via landing gear over 100 meters and I could still feel the pull of the connector on his little ship. I tried flying up, down side to side.

-When I went about 10 meters from the ground and unlocked the landing gear, the bugged ship was pulled toward the station connector.

-We ended up shooting it with gatlings for we determined it was cursed. (owner agreed and shot at it too)

-My friend gave him the miner we brought as a gift.

try shutting off the base connector instead of the rubber banding ship's. That's fixed it for me before.

Hi guys,

Still no luck in finding reliable steps to reproduce this issue. Any additional information would be greatly appreciated!

Thank you.

I have this bug then try to dig on asteroid. Ship stick to it. But not in all servers.

Should be fixed in version 188. Please let us know.

Hello, Unfortunately this is happening to me now on the official Keen multiplayer server so I do not believe it is solved.

I'm waiting out the 15 minute log off timer to see if it has an affect at all -

I'll post results once I log back in.

We too could not get our large grid disconnected from the connector, but turning it off did the trick, so we added an on/off button to the hotbar.

Definitely still happens in latest update, I uploaded a video so you could see etc.

Version 1.188.024 Space Engineers

(My record video key appears to be the admin menu key bind so just ignore the red text!)

https://youtu.be/wg0rc6p47MI

This is on Keen AU 2 etc.

Try switching it off, the ring will turn red.

Had this happen again on my local DS. Small ship with a connector docked to my base (on Mars)

Turning off the connectors had no effect. Grinding off the connector on my base had no effect. I had to grind off BOTH connectors in order to free my ship.

This happened after a server restart. before the restart my ship was docked to the connector charging its batteries. I built the ship from a BP during my previous session. ex:

1) start server

2) build small ship projector

3) load BP into projector and weld it completely

4) dock ship to connector to charge batteries

5) "use" the ship a little - fly around, shoot stuff, haul cargo, etc.

6) dock ship to connector.

7) log out of server, restart server.

8) log back in. try to undock ship - Fail

Not solved, just had this issue happen again.

In my post, which they asked be created if someone experienced this issue again, I discovered that it had to do with ownership of the parts of the connecting ship. Setting the owner to the one piloting resolved it for us.

Happens here also. Multiplayer, DedServer.

Why is this flagged as "solved" ? It clearly is not !

Just had the same problem, multiple time in a multiplayer session. I could sometimes escape by turning the connector off while connected.

Also running into this on our dedicated server. I think the dedicated server needs some love from the devs. The single player experience is pretty good, but there are so many more bugs related to multiplayer.

https://plays.tv/media/clip/5d0f39322353846853 seems to happing a lot now even after I seemed to fix it the ship went back to the ground at the end of the vid. only thing I did to make it happen I can think of is I built a little of the ship when it was docked

I am also experiencing this issue. IT happened to me twice once to a ship a friend made and once to a ship I made. This issue does not appear to be solved.

I am new to the game and encountered that issue as well with my very first ship today, which is really frustrating.

This is happening on a dedicated server, set up by a friend. I was able to escape two or three times after several tries of getting in and out of the ship, turning connectors on/off and switching lock-state, but as soon as you reconnect to the base-connector after a mining run, the ship will be bug-locked again. Also attempts to burst out immediately after unlocking, then leave the ship mid-air, resulted in the ship teleporting back to the former locked position. This is still true with both connectors removed.

I can't confirm this issue as solved.

I agree with previous commenters; this issue is not solved (or there is another issue with a similar effect but different root cause).

We still have this issue too on our server as of today.

If you voted on this bug already, vote on the new listing here:

https://support.keenswh.com/spaceengineers/general/topic/connector-bug_1

This issue is not solved, the same thing is still happening

Definitely still happening on my dedicated server. Its a super inconsistent bug, and a server restart usually fixes it.

Hello, Engineers!

Thank you for your feedback. To reproduce this issue we need exact steps to reproduce in an unmodded world. Could you please provide us with a save with a video and steps to reproduce?

We will appreciate any additional information since this issue is very difficult to reproduce.

Thank you for your patience!

I think the best I can do is say that I've confirmed that it only seems to happen with the downward facing connector. I redesigned the ship to have the connector facing back rather than down and the glitch stopped entirely.

Currently happening to me on an unofficial vanilla server. Setup is a base on a planet with a utility ship connected to it. Some thrusters broke so I replaced them via projector blueprint. Then I noticed that the new thrusters don't produce any thrust, so I reconnected and that fixed it, but then I noticed connector rubber-banding for the first time after a day or so playing. Reconnecting again fixed it, but the next time used the connector it got stuck again and reconnecting to the server now doesn't help any more.

Next I tried was pushing P while rubberbanding and lost connection to the server.

I have exactly the same issue described in the original post with a very similar base/ship design. I'm on a private multiplayer server with no mods in experimental mode (scripts enabled). Have tried removing and resetting ownership of both the ship and the station, grinding and rebuilding both connectors, and all manner of disabling blocks, toggling the lock state, etc. The only fix is a server restart which is extremely inconvenient for my friends playing with me. This bug seems to occur once every couple of play sessions and is extremely frustrating (doubly so since it requires a server restart to fix).

Hello Everybody,

Got same issue here. On modded server. Connected small grid ship to base connector (large grid). Turned off the thrusters (atmospheric). Then removed two big atmospheric thrusters and built two new ones. After disconnected, ship slipped to the ground and got stuck (landing gears autolocked). After unlocking gears and moving few meters away, ship teleported back to spot, where it was. Grinding both connectors had no effect. Waiting now for server restart.

Same issue here. I'm not sure how to reproduce it as it seems pretty random. It's rare though but extremely annoying. Save / Exit /Reload work but not practical and not possible when playing MP.

Stopping both connectors and even grinding them do not resolve the situation.

Still happening. Anyone got a fix for it?

Me and my friends are currently stuck with this. Have lost 4 ships to it. This bug has been repeatingly reported over about 1 year now and it still is in game. Do the Devs even care anymore since "full release"?

I quit the game and had to stop recommending it because of issues like this. Doesnt seem like there's any concern over bug fixing anymore 🤷‍♂

who knows. Not hearing about the pressurization bug any more either that still is ingame since early 2019.

Rather releasing a new DLC every few weeks to keep people busy :)

Keep pushing this post here so KSH knows about the issue. You have my vote

still happens in 1.194.048

Still happening no multiple dedi servers, no mods, multiple players and several internet connections, un-play-able.

Having the same issue. Ship currently rubberbanding on connector. Admin restarted server, ship worked fine, connected back to the connector with newly spawned blueprinted ship. Did some changes while connected. Was able to lift off, mined some ore, flying back to base my ship completely bugged mid air, all power was lost and ship was nearly destroyed. Note: upon take off it wasn't the battery. I was 17 day energy span.

Having the same issue. On my client the ship is moving up after I detach from the connector, however others on the server don't see the ship move. The session is pretty laggy. It almost feels like the command to detach isn't being replicated on the server, or is being dropped (I've noticed a few other key presses being dropped). That would explain why the server is correcting the position back to the connector, because it thinks the ship is still attached...?

Having the same issue regually here and can provide a save if you still need more data.

I am running a game localy on my machine and my friend is joining over steam. fairly often when he atempts to undock a ship from the base and fly away he keeps bing pulled abck to the connector, On my end he doesent move away from the connector and the ship doesent move. (as well as connecors this also occurs with langing gear). Have tried toggling various options on cockpits, disabling/removing connectors and none allow the ship to move, The only workaround I have found is If i get into a ship I can move the ship away from the connector and he can then fly the ship away, this is fairly reliable. Restarting the server also sometimes allows ships to start working.

I have also encounted the issue however less regually, When I encounter the issue I dont get any rubber banding the ship just doesen't respond to commands mousemovements/wasd commands.

This is one of the topics that I am still writing about, precisely to know how to be developing the NETCODE of this game.

Perhaps the only way for keen to reproduce this problem, is to simulate a bad connection, which loses packets between client and server. It is from there, to know what to do to make the code more tolerant of connection failures.

I get this issue exclusively on Multiplayer, when using the hotbar, "P" or terminal to disconnect. Using scripts to disconnect works perfectly fine. Its like the client thinks its disconnected, but the server has other ideas.

Same issue on a dedicated server, playing on LAN. Ship rubber bands back to base after a few minutes of flying away. I notice it when I toggle the Dampeners, *poof* back to base.

It's been happening a lot more lately mmm the server I play on, mainly because we are all docking on connectors to a starion at the same time. Seems that's when it's been happening the most. We are all in the same faction.

As a temporary solution, have you tried decreasing the "Strength" on the Connectors to see if this helps?

This is common problem.

Solution: Unlock the connector and then turn off the connector. Then you can fly away and turn the connector back on after a few 100m. Problem usually goes away when the server restarts.

I had the same issue last night on our dedicated server with two different ships.

- Ship jumped back to the connector the moment you enabled dampeners. Noone else sees the ship moving though.

- powering/depowering connector on ship did not fix it

- We 'fixed' it when someone else got in my ship's cockpit and then moved around a bit. Both cases this resolved the issue without restarting the server.

Go into the cockpit, leave it immediately then reenter it and unlock the connector. This has worked for me, it may take a couple of tries sometimes. Im superstitious and never press "P", it seems to make things worse. Instead I have the connectors and landing gears on switch lock in the hotbar

unfortunately that has not worked, pretty much all the mentioned solutions/workarounds don't work or consistently work, what does work is a server restart which is not a fix.

This includes server with cscripts or experimental mode on and off, ive tested this on multiple VMs and physical machines hosted for me and within my lan or directrly from my own machine and whats consistent there are the issues, its quite frustrating.

Maybe its time for someone more Keen to jump in and assist?

A workaround I found in my last session when my ship wouldnt move was to undock then fly away from the ship (about 3k or so seemed to do it) then it was flyable on my return. I assume this caused the ship to be unloaded and then reloaded by the game. might work for other people as well.

I'm having this issue and I'm not even connected to anything - I'm literally sitting on bare ground and can't take off. Only fix is to restart my (unmodded) server.

How is this not fixed after two years?

Money, that's why.

I have been having this issue since i got the game and i still am... it's the biggest problem i have with the game at the moment.

When i try to disconnect from the connector port my ship gets stuck and rubber bands back to its poison on the port and i can not get the ship to disconnect, In other cases i have disconnected from the port or at least i thought i did only to fine i wasted 20 minutes of my time travailing to a destination then exit the cockpit and within a split second fined my self back in my base as if i had never left and i fined myself now always disconnecting from the port and then jumping out of the ship just to check i have disconnected from the port something i should not have to do you would think, i am now always adding buttons so i can toggle the connector block off on the static grid in case i need to turn the power off to disconnect it, it's becoming a pain to keep doing this.

From what i can tell i think it is the static grid causing the issue for me, in a test i did i turned the connector port off on my ship but i found i was still stuck on the connector port but when i turned the static grid connector port off i was able to get off the connector port, i am going to do more testing with that.

i have a video of the issue, Video here

I also am having this issue. Even had it happen to my player where i couldnt run and if i jet packed it would yank me back to where i was like on a rubber band. It isnt a snap back it pulls you and when you get closer to where you started the pull slows down.

I have this issue when playing on my friends PC literally every single time I undock a ship. Sometimes even when not docked and I just unlock the landing gears.

Sometimes it behaves like the connector is pulling my ship towards it, no matter the range of my ship. Sometimes I can fly around, but after a certain amount of time I am spontaneously reset back to the position I was in when I undocked.

From the perspective of my friend the ship never undocks and therefore stays in place the whole time, even when I am flying around.

I found two ways to circumvent this: either I relog every single time I want to undock a ship, or my friend has to undock the ship for me, after which I can normaly fly around until I dock it up again.

On once occasion I couldn't even move my character anymore, not sure if that is related though.

Dude, this has been happening since the game was born. Keen has done nothing to address this, despite the evidence here in this thread and others like it. Keen has not even acknowledged the bug at all. I, like you, left because of this bug and many others just piling on top of each other, compounding, until....unplayable.

Very unfortunate because I love space engineers, I want to love space engineers. I sort of do?

All 6 of us stopped playing because of "bugs". But this one, especially killed the vibe.

Thanks.

we are running vanilla and are still getting this. can confirm this is vanilla bug

Bug occurring constantly between me and 2 friends. Vanilla survival server. Running off my machine while playing. VERY VERY annoying, every time they want to fly away, I have to hop into their cockpits and disconnect their ship and fly it vertical so they can take off.

Otherwise they just rubberband back to being stuck on the connector even after being several hundred meters away.

still an issue, no surprise there. Please fix Keen

I am unsubscribing from this and other topics so that I no longer pollute my mailbox.

Good luck to those who still have the energy for it.

You must think someone reads this thread! Haha.

Safe travels.

I have experienced this same bug for a long time, and it's started happening much more frequently for me on dedicated server since 1.197. this happens frequently when I am undocking small grid AND large grid ships from Station grids. Keen support, what other kinds of information do you need from us?

It's still going on for me too. Local LAN DS, so it's not a lag issue.

I can confirm this still happens on dedicated server 1.197.073, last experienced bug on 12/25/2020

Can confirm this bug still occurs. Experienced on Keen official NA servers as well.

The only 2 ways I know to work around this bug currently:

1. Have another player undock the ship and move it for you.

2. Get in your ship, unlock the connector. and log off the server while still in the cockpit/control seat. Log back in and you should come online in the ship but be able to move away. Seems like you need to both stay in the seat and leave the ship unlocked. Relogging outside of the grid doesn't work for me.

Still had this bug yesterday when playing with a friend on his local game instance. We both had the issue on the same station, and I even got stuck on trading stations literally every time I docked on one.

Several things I noticed about this bug:

- It does not seem to appear instantly. We did not have issues in the first few days of playing. It seems it requires a certain amount of ships being docked somewhere. Also restarting the server always temporarily fixes the issue for a few minutes.

- Switching off thrusters and then undocking so that the ship goes into free-fall often solved the individual perma-lock issue until the next docking, but only withing earth gravity.

- When I got stuck on Trading stations I learned that if I leave the cockpit and unlock the connector manually while not being in the ship properly undocked a previously stuck ship.

- The other player was always able to undock the ship properly no matter who got stuck. So this bug is player related.

- Switching off thrusters always re-synced ships, which usually 'teleported' me back to the docking port. It did not however always solve the perma-dock issue.

It is obvious that the issue's main cause is that the undock-command is somehow not accepted by the server, at which point server and client go out of sync until a re-sync event occurs. As we had otherwise zero lag nor any connection issues, I assume that this is caused by the client wrongly assumes that the cockpit is part of a different grid, and the server then ignores that undock command for a grid that the player cannot actually control.

Confirming heavy issues. It was gone for a few weeks now, but since the last update (1.197.075) it is nearly on every of my ships and repeads continuesly.

I think its all a waste of time boys. They will just keep responding with "Mods" and "Can't Reproduce" when no one even tries to reproduce apparently because its such a rampant bug.
