The last two times I have done this event his corpse poofs. It also is different.
During the watcher phase it use to go clockwise starting at 1 and moving around the room clockwise. This time it started at 11, then 9, then 10, then 8. It then basically went counter clockwise.
The rest of the event seemed normal. Got Aiveyn to pop after the staking the the corpse poofed.
