Ascalonian Catacombs Path 1
This just happened to my team as well. He actually bugged out twice in about two hours, the first time he bugged out before you gather the scepter pieces. We disbanded and leader entered another dungeon and came back to reset it. The second time he bugged out on the final boss, it would not complete. After two hours of playing and no rewards this person is not a happy camper.
