In the beta, whenever I try to choose a custom skin, it just shows me a black skin, in every online server, such as the InPvP beta: beta.inpvp.net , every player using a custom skin is inviisible. Please fix it because many players want their own original ideas and want to use custom skins. Please fix. I tried to choose the other custom skins but all of them have the same problem. However, this is not affecting the in-game skin, packs.

I hope this is taken into your notice.
