if you remove the armature it works so it had to be the armature. I methodically kept removing bone after bone until it worked on 2.92. Got through all the bones and still no go. The only thing left for me to remove was the subsurf modifier that was attached to the armature some how and TAH DAH!
EDIT: I couldn’t find a normal way to remove the modifier. I ended up making a new armature and merging Reds rig into the empty one with CTRL+J. That removed the modifier stack. I had to recreate the “rid id” property under the armatures custom properties (this makes the script work to turn the control layers on and off) Then remake the bone groups. Seems to work as it did before…hopefully I didn’t break anything further. Adrian I sent that off to you until Wayne probably tells us there was a checkbox somewhere that fixes it haha.
