I don't know if this is a bug or if it was just me being stupid...
I picked up the quest, somebody else in the group who was also doing it released the first prisoner, then the second, then the third... by the time I realized what was going on the dungeon was already over cause... you know... some people just seem to want to go through dungeons without even blinking and basically kite you the same way they do enemies.
The thing is that ALL prisoners were released and ALL bosses were dead but I was stuck on the first prisoner's dialog and the quest wouldn't advance. Now like I said... I don't know if this was my fault for not talking to them earlier or if the quest just bugged out on me.
I did try to talk to her before the sceenshots point but her answer was always the same.
