I have a similar "haunting", it's at Camp McCarran... I have a glitched quest "I Put a Spell on You" there and the spy doesn't ever move from the one spot so I thought maybe if I shot him and went back into the camp he would chase me in and it would un-glitch the quest for me. Two things happened.
1) It did not un-glitch the quest
2) When I was running back in the building I was being shot at and must of gotten hit because now, coming out of the door is a constant fountain of blood and a sound that repeats over and over like bullets hitting metal.
It's kind of cool in a way, but just shows how buggy that base is. I get a lot of freezes right at the gates of that base when I walk in.
