I too have encountered the game breaking bug during "Dangerous Minds". Bethesda will offer no council and refuses to acknowledge any issues. It does not seem to matter to them that we paid for their game. Literally this is killing me, all the time and fun I had with Fallout 4 and now its all worthless because I cannot move forward in the main story.
I hold out some shred of hope that Bethesda will offer some guidance, some light in the darkness. It is literally tearing me apart how badly this has ruined my experience.
Forget this Fallout bull crap, I am going back to Skyrim...Bethesda you have ruined it for me.
