I’m trying all sorts of things at this point. But here’s an odd one. I hid all of the islands that were behaving fine. So I’ve only got the bad ones visible. Strangely enough I can paint on this one face while in the 3d viewport. The rest of the faces within each of the island are misbehaving.


I might create an iterated save file and try remodelling the armpit to see if it occurs again
