Multi-Grid Physics Desynchronization After Undocking
Title: Undocking One Grid Causes Other Connected Grids to Physically Detach and Clip Through the Parent Grid
Description:
I encountered an unusual physics issue involving multiple ships connected to the same grid.
When I disconnect one of the attached grids, some of the other grids that I did not disconnect begin to physically separate and move abnormally.
What makes this issue particularly unusual is the inconsistent collision behavior.
Observed behavior:
- Multiple ships (grids) are connected to a common parent grid.
- I disconnect only one of the connected grids.
- Some of the other grids, which were not intentionally disconnected, begin to physically separate and move abnormally.
- These affected grids appear to ignore collisions with the parent grid they were originally connected to, passing through its structures.
- However, they still physically collide with the disconnected grid and the player, producing collision forces and potentially causing damage.
Expected behavior:
Disconnecting one grid should not affect the physical attachment or behavior of other grids that remain connected.
All grids should maintain consistent collision behavior regardless of whether another connected grid has been disconnected.
Possible issue:
This may involve an inconsistency between grid connection state and physics simulation after a docking connection is released.
The affected grids appear to behave as if they have become physically detached, while simultaneously ignoring collisions with their original parent grid.
The exact underlying cause is unknown.
Video evidence:
See the attached recording demonstrating the abnormal grid movement and collision behavior.
I have the same bug
I found another potentially related bug involving grid connections.
The grid setup is:
Grid 1 → Piston → Connector → Connector → Grid 2 → Rotor → Other Grids
When I connect Grid 1 and Grid 2 using their connectors, Grid 2 suddenly moves to an incorrect position.
However, the other grids already attached to Grid 2 remain in their original positions.
When I disconnect the connectors, Grid 2 immediately returns to its original position.
I'm concerned that keeping them connected for too long might trigger the abnormal rotation and physics behavior reported earlier.
I've recorded a new video demonstrating this issue. Please check the link below.

Yep, docking breaks the game..

I have experienced something that may also be related.

yea, do not get in the desynced ship. it'll brick the save. i've made a report here : https://support.keenswh.com/spaceengineers2/pc/topic/57525-desynced-ships-bricked-world

I have the same issue in combination with another one. When the smaller grid is docked, the mothership will fire thrusters and move in various directions when just steering via mouse (pitch/yaw/roll). As soon as i undock, this behaviour is gone but the desync of the small grid happens, as described above.

Ran into similar problems, mostly at some point connector lights up but wont connect and go green.
After that happens game restart helps, but one time Philadelphia experiment fusing occurred. No teleportation tho xD
For those docking bugs the game is basically unplayable,
after alot of restarts and reloads and i made to Obliviara sector.
This game is just so good im willing to suffer.
Looked for Aquila for 15min in space because landing gear just released and sent it drifting.
Found it tho :)

I agree, the bug really hinders gameplay. You simply can’t create a mother ship to which a collector, a добытчик, a dismantler, and others will be docked.
Personally, I’ve encountered the problem that not only the network lags, but the ship itself that carries the daughter ships also lags. Its physics simply break down, and the ship starts to wobble and accelerate in various directions even with a simple mouse movement.
Sometimes the ship may simply stop responding to controls, but when you exit it, it will be teleported, presumably to the place it flew to when you were pressing the buttons...
I really like the game, I’ve been playing since the first part, and I hope for a quick fix.❤
