using moon animator.
It makes me genuinely angry to spend all this time for it to break like it!

I just wanna like ahhh

Is there any way to revert it or make this not happen again?

Update: I manage to fix it by updating Moon and creating a new rig afterwards loading the same animation into that rig which seemed to fix it.
