For some reason, sometimes when I check my Marketplace characters, they change in looks without my permission! What's weirder is that only the mouth, eyes and hair change color. When the change does happen, it's always consistent with it's choose of colors. A ginger brown for the hair, solid blue eyes and a black or very dark brown mouth.

It has been happening for a long while and while I can play with my skins unchanged, it's unclear when they changed to the appearances I listed. In worse case scenario, the character's clothes may also change without permission too. 

The screenshot shown displays what my character looks like and the somewhat blurry picture displays the changes to my character. (The character's shoes have been removed for two characters)
