So recently i had a problem with being a Vampire Lord and still being attacked by npc's in and around whiterun when in human form (only Whiterun and Dawnstar where tested. Whiterun came with negative reactions from the townsfold and Dawnstar had no negative reactions from the townsfolk). The problem i realized (much later though) was that i was a normal vampire from the base game and too late i realized this and i couldn't cure it conventionally without killing people. Without at first knowing the cause i realized there was a problem. I did some testing and realized that even though stated otherwise some of the regular vampirism faults come around in vampire lord even though being a lord should replace the normal vampirism. The problem is that i accidentally became a vampire (as many people should considering the high exposure to vampires) while on the dawnguard questline so as i went through i didnt notice the problem untill it was too late. Through lots of research on my part i came to realize that i had to cure my vampirism somehome without going to morthal. I figured this out. The fix requires console commands so those who hate using console need not use this. Type setstage 000EAFD5 10 into the console and the regular vampirism gets cured just leaving you with the vampire lord power and unarmed buff. Note that some people from castle volkihar will consider you giving up vampirism to be mortal untill you first change to vampire lord again (not that that wont happen eventually) Edit: If you found my fix helpful please tell me on this thread (please no threadromancy though). Also notify me if this solution failed in some way as im still testing the problems solution ingame as i type this.
