Forum:Inexplicable hostility from NCR after BoS quests

I don't know what really happened, the NCR suddenly became hostile to me. And nope I wasn't having bad reputation with NCR (They accepted me) Nope I wasn't wearing any faction armor, nor was my companion (Veronica) I never even did anything or any mission that cause NCR to shoot me. I even dismissed Veronica seeing that NCR might have grudge with BoS, and the NCR still shoot me on sight.

The only I can think of is that it happened after I did BoS quest (Still in the dark) and helped Hardin ousted McNamara, and then cleaned out Van Graffs in subsequent loyalty quest and was declared a BoS paladin.

Shit I did that just to get power armor training early and I wasn't planning to be NCR's enemy. Now I couldn't even meet Cassidy in NCR outpost!

Please help!
