I can't reproduce this using only MCA Reborn and Pufferfish's Skills. Maybe it is a conflict between 3 mods, but it is hard to tell which ones.

EDIT: Removed every mod and still no skins, its ether one that we had different versions off or multiple mods with the same issue (had this before with a load order issue)
