Minecraft version - 1.20.1
Mod loader - Forge
Mod version - 1.8.1
I am using the latest version available - Yes

Was playing my updated 1.20.1 pack, and when i tried to log in i got this message? Not sure if it's better combat, or this other mod i'm using called 'Just Leveling'. It's not a fresh world as i've been playing it smoothly for some hours now.

Crash report:

"Just Leveling" is performing mixin on Better Combat, meaning it alters the code of Better Combat, leading to a crash.
Mixins towards other mods are completely unsafe, and not supported at all.

I see i see. Ima go msg that just leveling guy about it then. tyty.
