In my game if I enter my home my spouse will say "help" if I try to speak to her it gives me a rescue quest to help her and kill a vampire but there is no vampire in the cave I am told to enter which means I cannot complete the quest. I have also tried to fix this by getting the quest from Florentius in fort Dawnguard and this time it gives me the same cave and my spouse is inside allowing me to free her but again there is no vampire just a marker in the air over empty space preventing me from finishing the quest or getting anymore quests from the Dawnguard I've tried everything I can think of anymore help would be great I really want to fix this.
