I was playing with a full fireteam, the final encounter in Duality where you fight Caiatl. When ringing the bell to go to the nightmare realm to get the standards, about 1 in every 6 times we rang the bell it would just wipe the whole fireteam and restart the encounter. The following were true every time this happened: - One player was standing on each of the two platforms indicated by the standards showing on the floor - The third player was on the floor and shot one of the bells to switch to the nightmare realm We didn't see any correlation with which bell was rung, or which platforms we were standing on. I have run this encounter many times and have never seen this happen where the whole team gets wiped. I know there is a bug that can randomly kill a player if they're standing too close to the bell when it rings, but in all these cases no one was near the bell. This was really frustrating because we were guiding a new player through the dungeon for the first time and after five attempts to complete the encounter, we finally gave up because it was happening too frequently for us to finish killing Caiatl.
