So I was at the point where I had to choose between factions And I either had to go talk to the brotherhood, minutemen and the railroad. So I decided to go to the minutemen but before doing so I went to kill off the railroad and the brotherhood (dont ask why I just felt like going on a spree). Then I went to talk to preston but.... for some reason he just ignores me the dialogue options dont pop up I have tried everything from sending him to another settlement to attacking him.
Also for some reason all the auto saves that I have are from after I killed of the brotherhood and the railroad and the last one before that was from a week ago.
How do I fix preston, anyone have expienced the same?
