This mission bugged out on me back near the beginning of Live play (basically a year ago) on my first character.
I can clear the mission up to the point you have to talk to the captive and then lead him to the utility room and open the door to restore power. The problem is that the door is already open (opened it on my initial run of the mission and then died to the boss). The NPC does not recognize that the door is open and just stand there. Mission will not advance past that point.
It has been that way for about a year now. I check occasionally to make sure. My other characters have completed the mission.
Is this ever going to get fixed?
