Forearm twisting issue
I'm trying to clean up some animations in blender, but when I import them back in they have this: 
I can't seem to find anything out of the ordinary on blenders end as there aren't any abnormal keyframe jumps, and the armature doesn't deform like this in blender either. I think it has to be on Unity's importation but I don't know where or what. It's only a few keyframes where the character raises their arm above their head.

I ended up downloading a rokoko addon that allowed me to retarget the animations in blender and export with the same rig, which solved me issue
