I was in the quest "nuclear option" (for the brotherhood) when I got into the institute and cleared out the main area. I then was instructed to go to the directors terminal. I went into the elevator and it took me down. Before I could get out of the elevator it closed again and brought me all the way up. I went back down to the main area and I clicked the elevator button again and it said "elevator access denied." I spent the next hour looking for a way to get down to the directors terminal before I had a friend help me. He said it was glitched and the elevator is supposed to work. I tried to just leave the institute but there were shutters over every doorway. I can't leave the institute, the elevator isn't working, and all my saves are from in the institute. Is there a way to reset the mission or am I going to have to wait for a patch?
