So I've chosen to go with the railroad. When i start The Nuclear Option it tells me to first talk to Desdemona, then to go to the institute and talk to Z1-14. When I go to the Institute the game lags for a second as it tells me all of the institute missions i failed by teaming up with the railroad, and then it checks off the "Speak to Z1-14" objective even though I did not talk to him. When i attempt to use the elevator to go to the relay room it tells me i do not have access, and Z1-14 is nowhere to be found. I have loaded and retried this several times, every time i get stuck at the same point. Am i missing something or is my mission bugged and impossible to complete?
