I honestly don't know what happened, other than it ended up in a stack overflow after ticking me. The crash log is attached
crash-2022-03-23_14.45.37-server-copy.txt
.

I don't believe this to be an issue with Clumps, we don't touch the method it is overflowing on at all, I believe this is an issue with Tetra that was fixed fixed mickelus/tetra@e56d429

Try with this jar file and let me know if it fixes the issue https://www.curseforge.com/minecraft/mc-mods/tetra/files/3711077

Closing due to no reply and the issue being with another mod.
