So today I decided to make a headshop on creative world 1 (I haven't tested on other worlds) but when I tried to get heads from a very long list of minecraft youtubers of about 40 people, about 75% of them gave me this weird orange haired guy. Only some youtubers worked like: sky does minecraft and its Jerry and its Harry. Many other random names I put in did the same thing limiting my headshop to only 18 heads!!!
1. The 'weird orange haired guy' is a new player model called Alex. 2. Make sure the username has not changed. 3. Basically like Warden said try 1.7 because the server still runs a 1.7 backend.
The orange haired guy is indeed the new player model called Alex. Not sure why some skins don't display correctly, I don't think there's much I can do about this until we update to 1.8 backend
