I was doing Onxyia 10 in Lordaeron earlier today. I had Master Looter. My internet went off during the second phase. I managed to log in after 60 seconds, and my character appeared outside of the dungeon. When I re-entered, I couldn't loot Onyxia at all. I tried passing master looter to another member, changed to free-for-all... nothing. Didn't even received emblems.
I know this is a known bug; however, is there a temporary workaround in case this happens again?
