So I've narrowed my problem down to the root cause, but because of where my saves are I can't fix the issue myself.

This regards the 'The Nuclear Option' quest. I reached the quest with the Brotherhood of Steel. Now after I plant the explosives within the institute, I am supposed to get teleported back to the control room so I can speak with Kid Shaun. Now what happens to me is I get teleported back outside where Liberty Prime first made the entrance into the Institute. Once here I can't go back into the Institute and I can't just leave the area without my game crashing.

Now I checked my active quests and I've realized I still had an older quest I never got around to completing. After meeting Shaun for the first time I was supposed to meet the people that were the leaders in the Institute's various departments. After meeting these people you get a quest objective to leave the Institute. I fast traveled from this location and I never got the completion for said quest.

So I'm guessing since it's an active quest in the mission I'm currently stuck at the game thinks I'm leaving the Institute for the first time so the teleporter sends me outside instead of into the control room.

This is extremely aggravating, but I'm not losing hope yet. I have hope that this predicament of mine has a fix. I've spent so much of my time on this saved file for it to just be lost to me. If anyone can assist me that would be amazing. If not just take this as a caution so you guys don't do what I did.
