If any players are positioned where the exit portal spawns on the final boss of Murozond’s Rise when the boss dies, they will be teleported out of the instance immediately and become ineligible to loot the key’s reward chest. It despawns after the remaining eligible players have looted, no loot is mailed to the affected character(s).
I have two unlisted videos of this happening; one is still processing.
First Video Terrible floor POV
Second Video Best POV - two players affected
