It has been years since I did this quest last. I attempted to do it last night on a PoM that just hit 80. After clicking on all of the sarcophagus and the tombs, I fought and killed a bug like guy (The old one or something). What do I do after that? Journal didn't update. No white text telling me "more foes on the way". No cut scene. No loot drop. No spawn. I just ran around and avoided the wave coming out every minute.
What am I missing?
