I dunno if anyone has noticed this bug before, anyway, I found it quite usefull ;P

Im one of these rogues that never pickpocket mobs, and therefore never get any lockboxes to train on, but yesterday something wonderfull happen, A lvl 57 Blood Elf Rouge (Whom apparently is a lazyassrogue as me) Traded me and asked if I could open his lockboxes, Ofc I said, and I demounted and picklocked at the same time, and to my surprise I got a skillup, and I looked in my combatlog, and there it was! I had picklocked my MOUNT!.
