When a multiplayer world is joined, every player looks like the default "Steve" Minecraft skin on the screen of the other players. One appears normal on their own screen but everyone else is "Steve" and they are seen as "Steve" to the others as well. 

The skins didn't always function properly with the previous update (Occasionally two people would have the same skin if someone changed mid-game), but now nothing is working. It was attempted to change skins mid-game or leave the world and rejoin but the bug remains. 

It is impossible to play multiplayer Minecraft like this! And seeing as I practically use Minecraft solely for Multiplayer, this is an extreme disappointment. I'd prefer to have never gotten the update at all.
