I installed the mod and attempted to open the identity menu. when I did, it immediately crashed. upon looking at the crash log, it mentioned something about the Piglin Brute mob, and when I reentered and tried to spawn one in, (thinking I'd need to kill one first for some reason) it immediately crashed again.

remove the bygone nether mod and try again...

I am also having this issue where my game crashes when opening the identity menu, but I have a different error. Removing my axolotl variant mod resulted in the mod working, but I wonder if there's a way to resolve this?
