I'm at the end of the DLC, facing off against the Mechanist and his bot army. After the countdown and the power fails , he tells Sparks (his Eyebot assistant) to"get the power on" - and the dialog stops. The power never comes back on, and Sparks doesn't respond to him.
The entire room remains dark. He sits up in that room, and I look at him, but can't talk to him, or proceed at all. I also can't elave the room. What can I do? Am I completely screwed? Any console commands to get around this?
