For whatever reason, when going over 30 layers of tattoo/body paint, some of my layers randomly get converted into other layers I'm already using. This removes the original shape that the layer was and it's placement. Then I have to go back through all my layers one by one to find the duplicate, remove it, and remake the original layer. This was a nightmare for me the other night as I was below the 50 layer limit, hit save, then looked at my character and it was butchered. Had to start all over and save and exit a little at a time and still had this issue at 30 layers. I do have premium. I'm not sure if this is a known/reported issue, but if not please add it to your list.
