That explains A LOT. We were trying to figure it out earlier and thought maybe it was just the game having issues again cause things randomly teleported, got health back, and the bells would ring without us touching them or wouldn't ring when we did shoot them. We also all 3 got booted out after about 30 minutes of getting wiped by the bells and random stupid things happening but so did others in chat that weren't in the dungeon with us. The snipers were being much more of a pain than usual also but we were all 3 arc titan and warlock.
