Describe the Bug

A crash on Forge 1.20.1 is making my current SMP unplayable for all members at the moment:
https://mclo.gs/85TBaIj
Null Pointer due to "track.edge is null". Is this a known issue? Can I do something here?

If you need any further info, don't hesitate to ask.

Reproduction Steps

I don't really know what to put here because I can't exactly say what action causes this error.

1. Be on my SMP with the required modpack
2. Go near the crash location
3. Experience the Crash

Expected Result

I expect to not crash I guess?

Additional Context

This crash always appears when I move close to a specific location on a track. I tried to land on a train contraption driving on this same track, and since then everyone crashes when coming near that location.
The train uses copycats+ half panels on the roof, if that is relevant.
