In the Chapter 6 Bodhi fight, Bodhi locks the door that commonly leads to the bottom floor of the vampire complex and announces something along the lines of "I wont fight you until you kill all my sons and daughters."
I'd do that, if I could only fight them - but though I slay everything in sight, she won't open the door. The 3 vampire coffins give me the "rotting carrion" response. I have few other mods loaded, just Kelsey and Quest pack.
On a side note, it seems that one of Drizzt's followers always gets charmed by the vamps. I was amused to watch Drizzt kill a charmed Wulfgar and then say "That fool attacks! Let us leave him unaided" and off they go.
