Indeed. I'd told my Pridemates to do their best to not go into the mail when I figured out what was going on.
I too did a couple or three checks, just to make sure, and yah... Looked like a glitch, smelled like a glitch... It's a glitch, and not just for Legendaries.
They roll back, they roll back. I got no probs with that. I'd seen some who were very, very blatantly exploiting this bug all day so far, and I've been in here for about 4-5 hours.
