Exactly what the title says after completing honest hearts NCR have become hostile (Even when it says i'm idolized by them) same with the cavaran company they dont attack me if I dress as them but I cannot complete main missions.
It problem after problem with this game. I love the series and this game but the software dev's are so slack its unreal.

I think i heard about this glitch. I dont know how to fix it though. Its either a Bug or a glitch. Maybe go back to your last save(before you even started HH) Then maybe do it all over again? maybe im not so sure.

But it is a Bug or Glitch.
