Big grid rover wheels bug out (detach?) on load game

Darko Milenkovic shared this bug ago

Solved

Hello Keen QA team!

I will try to be as concise as I can...

I tried creating mobile base big grid vehicle rolling on a 10 5x5 wheels in local multiplayer survival game.

It generally went OK, with occasional clang, but mostly it was my fault that was easy to fix on my end. At some point the wheels started detaching from the suspension part, on game load, which caused the vehicle to spawn much closer to ground, and to shake like crazy to boot. Getting near the wheels will kill you and send your body flying in the air.

My "solution" to the problem was to have a landing gear on a piston, which will lock the vehicle to the ground before saving the game. This would ensure that the vehicle will spawn at the correct height when loading the game, and most of the time, the wheels would be fine as well.

Last update changed this - now if I have the vehicle locked via landing gear, not only do the wheels clang, but everything shakes itself into the oblivion. I removed the piston and landing gear combo, and added a bunch of 3x3 wheels, hoping they will help somehow.

No dice. What am I doing wrong?

P.S. i attached the whole save game, since I wasn't sure the blueprint alone would be helpful.

Kind regards,

Darko

Here's the screenshot of the detached wheel. The wheel is actually connected and the whole rover is shaking like crazy while the game tries to place it where it belongs.

Hello, Darko!

Sorry to hear you're experiencing this issue. Firstly, the world you provided has a number of mods and for testing purposes, I removed these to make sure these weren't the cause of the issue. With the mods removed, I had the issue with the current version of the game and also an older version. I couldn't help but notice my character when jetpacking felt off somehow like it wasn't really responding how I would expect it to. Due to this, I blueprinted the vehicle and pasted it in a fresh clean world and the ship does not behave like the original save file. I would suggest doing the same thing and verifying that you also do not have an issue. I would then say there may be something wrong with the world rather than the ship :) Please let me know how you get on.

Kind Regards

Hey Laura!

Sorry for not responding sooner, real world and all that :)

Unfortunately, this didn't really help with my situation.

I blueprinted the vehicle, and created a new, mod-free world, where I pasted it, and saved the game. After reloading, one of the wheels started bugging out on me, and the vehicle behaved just as it did in the prev world. Here's the video of the ordeal, in case it doesn't happen to you. Hope the Dropbox link is ok?

I will also attach the savegame file, like before.

Thank you for taking the time to help me, let me know what you find :)

Kind regards,

Darko

Hello, Darko!

Thank you for the video and save file. I can see that your save file has the issue again when I load it. I have tried to blueprint again, save and reload but it doesn't seem to have the issue again. Although I can provide the save file, I need to reproduce causing the issue to report it. (I hope this makes sense) Could you possibly try providing a bugged blueprint? I'll see if I can paste your version into a new save and try to reproduce it that way. It's really strange how it's not happening for me in a new file.

You can access your blueprints files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Blueprints. Select the correct folder where your blueprint is saved (local or cloud), zip the file and attach it here.

Kind Regards

Hey Laura!

I understand you have to reproduce the bug, to prove it's not something on my end, so the team can attempt to fix it, or to prove it IS something on my end, so we can all learn from it :) If nothing else, for possible future duplicate bugs.

I did some exploratory testing while playing (obviously), but I'm unable to provide you with the exact steps to reproduce the bug. Here are some observations, though, which I hope will be of use to you:

the weight of the rover doesn't seem to matter, as well as the number of the wheels attached
it happens both on my PC, and on my wife's laptop
it happens in both survival and creative mode
it's not the mods, since it happens with clean game also
it happens on both Earth Planet and Alien Planet (didn't try with others, but I don't think the outcome will be the same)
wheels bug out at random (front, back, left, right, there is no pattern), so maybe the elevation at the time of the load is playing an important role
grinding the bugged wheel(s) stops the rover form vibrating
it happens only on load game

Hope this is helpful, let me know if there is something else I can help with :) Thanks!

All the best,

Darko

Hello, Darko!

Thank you so much for the further information. I'm not sure what it was about this blueprint compared to the blueprints I was creating but this creates the issue every time! I have successfully reproduced the issue and reported it internally. Thank you for your continued efforts to help me reproduce the issue from loading a save - that's a great help :)

Kind Regards
