So i transfered my old DK from Cata to WotLK and started gearing up slowly. Last night I was doing the event dung. from SFK and my character got bugged so much that my game crashed. When I got in the game after a few minutes I realised that I lost all my talents and all my spells. But that's not all, I got teleported to the DK starting zone and i have to do the main DK quest line all over again eve though I am lvl 80.. Please can someone help I dont know what to do.
