I was doing the pagoda with a friend(levels 90 and 74) and we got up to second-to-last room and we had a problem with the four bosses and we each died and different times and had to run back. After 2 1/2 hours we finally killed all four and got the dialogue pop-ups, but the door to the last room won't open. Very frustrating to spend all this time and effort and not be able to complete it. I assume this is a bug, if not, players need to know if they die they cannot advance to next room/level.
