As I came upon finishing the game on the side of the minutemen, I was taken through the institute where I meet Shaun, and The Father. Upon finishing the dialog with father, something messed up and the dialogue reset itself, keeping my previous answers shaded out. Seeing as the dialogue was not a short one, I did not want to repeat it and decided to shoot and kill father. The game wouldn't let me at first, as when I aimed at him i couldn't fire.. but I discovered a second later that sidesteps and firing I could hit him, and I killed the father in one shot.
Upon achieving this, I was instantly told to flee from the institute and was ambushed by Synths. I retreated and left.. When I proceeded to the castle to talk with Preston, the Synth army attacked and the battle wore on. After completing this I progressed to the quests for the minutemen finale quest line, got into the institute etc. Blowing up the institute was fairly quick, as my cousin and I were playing the same parts on our consoles on separate tv's side by side, he hadn't killed the father straight out like me and apparently it jumped me ahead a full 2 hours of content from where he was stuck going through missions still for the minutemen in the institute. I only had to blow up one small reactor, him: two and some large battles in between.
Anyways, I have been reading up on ballistic weave, obtainable by the railroad starting quests.. A lot of people are saying that finishing with the minutemen should still allow access to it (many guides say this as well) and I should be able to access these quest lines.. However when I go to the underground HQ, Everyone is disgusted with me, telling me to get lost etc. I researched this and was only able to find one post saying this would happen if you did not evacuate the institute before blowing it up. Although as I recall I did issue the evacuation.. My quests with the brotherhood have also come to a halt. I'm not really sure of what I did wrong.... Help? I'd rather not restart as I'm almost level 60 with over 40 powersuits..
