Minor quibble, but figured I'd point it out. Ingjard (female Dawnguard Nord) doesn't appear to be properly assigned to the correct faction. I can attack her without interference from any other Dawnguard members (whereas attacking any other Dawnguard member sets the whole gang against you) If I pick a fight with Serana in Fort Dawnguard, Ingjard is the only Dawnguard member who won't join in on the fight.
