I just ran the lockdown raid and when we got to the last boss it locked us out and would not let us go in the final boss room. we kicked each member of the raid one at a time, and it still did not reset. no one was in combat, the door should have opened, we wasted over 45 mins in there for the game to kick us out.. -_-
You have 2 options, use pet after all are in fight room, or stay back and don't go near the door because pets take aggro of boss and if you don't join the fight room when you see the portal you still bugged out.
no one had any pets up, no one was in boss room we all warped to rally and tried that it just shut us out b4 anyone was in the room
I can confirm this, happened with my league the other night, we tried as many work arounds as we could possibly think of but unfortunately we had to start over with a re que.
