Hi, I'm working on posing this creature I made, and when I was painting weights I realized that somehow, I don't know when it happened, a piece of my geometry was missing. When I used a poly plane to fill the hole, and combined it to my mesh, my paint weights stopped working.

I now have a would-be interestingly posed creature, with the weights only half painted, and the smooth skin bind still in tact. (that's the confusing part. The skin bind is still there, I just can't paint weights. I even deleted the piece of mesh I added, and nothing.)

Will I have to delete the skin bind and redo the paint weights to fix it?
