I did the entire Dream Hive quest line, came out of the last one and killed the boss mob at the end (I really liked this series). But now I have The Arkella Estate: Find survivors at Fen Gorge Bunker. I went to the bunker, followed the blue check mard (it says it's completed) to the Dream Hive, and there is nobody to find or talk to. The dream eggs are clickable and send me back into the 3 respective dream environments, but there's nothing to find in there as far as I can tell.

If the quest is indeed complete, it needs the turn-in location shown after the survivors are found.
