I was shopping for Skin clothing in the newest version on MC PE, and all of a sudden, while changing my clothes, the avatar reverted back to the default Alex design.

It wasn't that my avatar just de-robed, but that my hair, eye color, and everything else reverted to brand new as if I never made an avatar.  I was taking screenshots at the time because I thought it was funny to see the newest mittens for the holidays were as big as boxing gloves.  Two seconds later, Alex stood where my avatar once was.

I don't mind redoing my avatar, I just wanted to report the bug.
