[0.17.11.0] Physics Items Don't Sync In Multiplayer

Having a bunch of physics items stacked together causes a lot of desync on other clients. I had a tower made out of physic blocks and my friends would always see it collapsed or really out of place, while it’d be perfectly straight on my screen.

Steps to Reproduce

Put a bunch of physics items together in a precise way, like stacking.

What I expected to happen

For all players to see them as the same.

What happened

Lots of desync between clients.

The only workaround right now is to disable the physics and re-enable them. It doesn’t sync things, but it at least gets it reasonably similar.

Does having the boxes undergo any type of movement mitigate this issue? I’ve previously made a fully physics powered marble calculator where the balls underwent lots of precise movement, and didn’t have many issues with this as far as I know.

It does not. In this case, the entire structure is built out of the physics objects and they’re all directly touching each other and resting upon each other.

Me and my friend screenshare our games to each other and what we see is very different. The starting position varies a lot, but each change does as well. Often times, the structure will fall over for them but not for me as the host. The structure is much less stable for them as well, jittering around a lot.
