Description

I switched my previously unmodded paper server to a archlight fabric modded server, manually installing the mods one-by-one while checking if any caused the server to crash or the world to corrupt (I had a world backup in case anything went wrong). Nothing caused any issues and the server's been open for days without any issues. But I noticed that the server will crash unexpectedly if I try to generate new chunks, specifially ones that should spawn a swamp/witch hut in them - why that's the case, I can't tell. Any other chunk will generate normally, if it should have a swamp/witch hut it's an instant crash. This doesn't happen if you run the game on single player (i.e. without arclight). Right now I'm even unable to join the server without causing it to crash, since when I do the world tries to generate a swamp/witch hut and crashes instantly.

Step to reproduce

1. Install arclight-fabric-1.20.4-1.0.4-80ec5df.jar as well as the mods and plugins (mega download below);
2. Run the server and generate a new world
3. Using the locate structure command, find a swamp/witch hut and teleport to it.
4. The server should crash immediately. If it doesn't, repeat step 3 with another swamp/witch hut (since worldgen isn't 100% guaranteed).
