Wheels are wriggling

I am playing on a private DS with some other SE fans met on a forum and I am using a rover I have designed for this. When I want to park my rover, it behaves weirdly. Two days ago I parked my rover next to the small base I had built and disconnected in my cryo chamber. When I came back the following day my rover wasn't anymore at the place I had left it. When I logged back on the server it was night time but after the sunrise I saw my rover several hundred meters away; I took it back next to my base.

We are playing PVE only, to be precise, so no griefing involved.

Then I logged out to eat and when I came back my rover had moved again. Then I noticed that the wheels were wriggling like english jelly. I put a connecter on my rover, and built a connecter with a piston on my base. When I came back this evening the rover was where I had left it, still connected, but it had a weird angle with the ground below. I proceeded to unlock the connector on the base side and it all went CLANG. I heard an explosion and my rover flipped over, half explosed.

I asked for a new one to be spawned and tried several workarounds to solve this. Neither switching off the programmable block with the Driver Assisting System script installed nor switching off all the suspensions stopped the wriggling.

I did'nt check if it was specifically a multiplayer thing or if it happened in solo as well.

Here is the rover in question, with a workshop link for the blueprint : https://forums.keenswh.com/threads/show-off-your-creations.6577447/page-171#post-1287112424
