Vingalmo keeps sending me to turn valindor or haran into vampires even though I already have and I can't turn them twice, so the quest is incomplete and I can't get any other quest from the other vamps in volkihar, unless I kill them, which makes it pointless why I turned them in the first place. I hope there's a patch for this problem coming cause I hate having unfinished quest lines. By the way, this is a very cool expansion, keep it coming Bethesda.
