My friend's custom skin turns to my own, and vice versa.

So for the past month or so (possibly longer), my friend and I have been annoyed at this MIND BLOWING bug. We both use custom skins that we've made ourselves, and both are very different. Both were made with our own interests AND REAL LIFE APPEARANCES in mind, so you can imagine why it's so frustrating that only one of us can use our custom skins at the same time. I'm usually the one who bites the bullet and ends up using some skin off the store or something. It's not necessarily a game breaking glitch by any means, but it's SERIOUSLY IRRITATING.
