Was in the middle of the "You Can Depend On Me" quest where you deliver the Crimson Caravan Invoice to Dr Hildren @ Camp McCarren, I was inside the building @ Camp McCarren and accidentally walked too close to a "restricted area" and now all the NCR on the base attack me on site even though I have good rep with the NCR...

I have gone too far to load back... What do I do?

I seem to have fixed it via stealthing in around the NCR troops and talking to the NPC
