Describe the Bug

While playing the game on occasion randomly crashes with a ConcurrentModificationException during Batching chunks. Disabling the flywheel backend seems to prevent these crashes. Edit: Crash still happens. This crash might not be flywheel related.

Reproduction Steps

This is a relatively rare occurring crash and seems to be caused by a race condition. As such there's not really a reliable way to reproduce this other than waiting. I'm close to a relatively large and dynamic create factory with plenty of chunk updates, which I suspect increases the chance of this crash occurring.

Expected Result

The game does not crash.

Additional Context

No response

This is most likely a bug in create and not in flywheel. Reducing the speed at which some of my contraption rotate and thus form and are placed back in the world seems to have solved the issue.
