My guild wiped on HM4 Four Horsemen last night.
When we returned to the boss room, the doors were locked.
We went and cleared two other wings and came back. The doors were still locked. We had to end up all exiting the raid, going and clearing AQ, and then return afterwards (then the doors were open).
Not complaining or anything. I understand bugs sometimes happen in this game. Just wanted to report this in case it was a new problem with the recent patch. We have not experienced this problem before in Naxx (in SoD at least I know this has happened in other versions of the game before)
If anyone else experienced this problem only after this recent patch, please report it here.
Thank you for your time.
