I've just activated the relay in the institute and the pop up to talk to Preston is there, yet all I get is his generic Minutemen dialogue lines, I've tried reloading saves, going back to a save before I even entered the building, i'm happy enough I can finally access the area after the initial crashes pre-patch but now I can't complete this game STILL. No clue what to do and hope to god I can finally complete this game soon.
