Just grouped up, ungrouped, and regrouped several times to try to do the daily normal level Undaunted dungeon (today is Vault of Madness).
A few of us have already ready completed the quest, one has not. However - the quest doesn't spawn for the person who hasn't done it. We thought nothing of it until we killed the Harvester Boss and the gate was closed and we couldn't get through.
The NPC that is related to the quest, Gasteau Chamrond, is laying on the ground near the beginning of the dungeon - and gets up holding his stomach after we kill the first mobs. we cannot interact with him at all... so have to press on. That's when we reach the dead end. What is going on here? I see this quest was bugged on PC last year too. Still not fixed??
