When playing on singleplayer world, custom skins work fine.

However, when playing on a two player lan game, both players view their own paper doll and third person view as looking like the other player.

On a server, skin will be fine when far away from others but will sometimes randomly change to copy that of another player's.

Can be temporarily fixed by changing to steve/alex skin, and then back to the custom one, but the problem still comes back.
