Tried to activate a water wheel with water on a server, game immediately crashed for all members of the server and would continue crashing every time when logged in and loading the movement animations, but server is still running. Managed to load into the server briefly, and blocks around the contraptions turned invisible. Crashed immediately after attempting to interact with the invisible regions.

Crash log:

Issue reproducible in single player with just water wheel and water bucket:

Turns out it's an issue with magnesium (port of sodium to forge) that wasn't listed in the modpack I was using :/. Works again after removing it
