Log: Crash Log.txt

The crash happens when the player is in 3rd Person with a custom model and a Jukebox is ACTIVE.

Going to add to this, the mod author of supplementaries confirmed that the issue is happening because both this mod and theirs has a Mixin for ParrotShoulderLayer and this mod is causing theirs to return a pose stack when it is suppose to be empty, thus the crash happens. (Disabling the mixin on their end fixes the issue which is what I am doing temporally until this issue is fixed).

was wonderin, how were u able to do this ? my friend tried but the crash didnt stop

they're telling me that them doing that just causes minecraft to crash

Open the mod with something like WinRAR then open the common-mixins file and remove the ParrotShoulderLayer (or something like that) from under client. It's directly above ParrotLayer.

It doesn't for me. Supplementaries runs just fine without that specific Mixin.
