Frór (yes, with the accent!)
I ran today with a group in Ascalonian Catacombs, path 2, and when we went to the traps room, the event start correctly, but after the quest’s breeder spawned, he simply didn’t move. He kept spawning gravelings as he should, though. When we started attacking him directly, we tried to bait him on the traps all together. In the end, he started to move but he never went closer to the traps than his spawn position. We could kill him, revive Detha and finish the quest that way, moving to the next quest.
Later that same instance, the usual Detha bug occurred (the one where she needs to speak to the Ascalonian Captain in the final room, but simply doesn’t find the quest point position).
If it’s of any indication,
