is anyone else having problems with getting through the Vampire quest line? i want to get the vampire quest line achievements out of the way so i can focus on the dawnguard ones after, but i cant get the next quests. after i get the vampire lord power, harkon tells me to get speak to Garen Marethi, but when i do he tells me "mortals shouldnt be walking around the castle, go talk to harkon". the first time this happened i went to talk to harkon, but he didnt even acknowledge me, then i disabled all my mods, but the problem persist. id rather not use console commands. if anyone knows how to fix this please, help me out.
