Hi all, I wanted to achieve some companion perks but I'm having issues with Preston.
I made lots of quests for Minutemen but eventually I sided the Brotherhood of Steel in the main quest line. Now when I talk to Preston he only says, and always repeats, about the fall of the Institute and why I didn't evacuate civilians...and usually he walks away while he's talking...
After the Nuclear Option I could get the Castle mission and all the Minutemen radiant quests but I can't talk to him normally like other companions nor recruit him.
