A hole in the horse's head, which appeared because the textures inside are empty (I wanted to cut off the griffin statue from the top of the horse, and a hole formed there because there was nothing underneath). For the Paladin, I fixed this simply: I changed the skeleton and geometry of the entire unit to the skeleton and geometry of the champion, but this won't work for the cavalryman because the rider isn't wearing a helmet, and making units with the same skeleton and model would be silly. I had 2 options, which I already asked about, and you, footman, have already answered them.
