Hi! I've recently discovered this mod which is like a 1.12.2 mod called Better Combat: Rebirth and apon loading into my saved world called Nina North the game crashes with this mod. Here's both the crash report and the log:

Crash report: https://pastebin.com/AgG13LKR

Edit and disclaimer: Mixin was already booted before the crash happened when trying to load onto a saved world so there's no need for Mixin Bootstrap and if I were to try to make a new world the game would've crashed still due to this issue that's within this mod.

Oh, 1.16,4, got it

done
