^ Once again you go way off topic.
Anyways, I can't see the picture with the URL you linked, but if it's the 'Pink Skin' bug/glitch, it is very common when changing skins to an Adult, or Young Child... If it was just a normal student you changed skins to, I don't know what to tell you and you best just wait until someone else can properly assist you.
But yeah, if you DID change skins to an Adult/Young Child and it's a pink skin.... That's why. Changing skins to an adult/young child causes pink skins.
