Still broken in 1.06. I cannot talk to Andraknor, everything is checked as done, I see the marker over his head, but I cannot talk to him.
If it's not fixed yet, I doubt it will ever get fixed...
For whatever reason, I ended up loading a save on the Nexus after I received the quest from him, but before I'd left the station, and definitely before I'd done the quest, and was rather surprised to find that he'd reappeared after walking away at the end of the first conversation. So I tried talking to him again, in case you could maybe ask him some questions or whatever.
Talking to him again without having finished the quest, or even left the station, gives you the same dialogue you get when you try to turn in the quest later. He calls you sister and everything. This is officially even buggier than I thought when the quest just wouldn't complete.
