hey so I bet that many of you have gotten this bug and it's very annoying. When I walked into my riften home a rescue quest was completed that I never started and when I headed back to fort dawnguard and asked what I could do to help, they directed me to Florentius. He doesn't have the dialogue option for helping the dawnguard and it's telling me to kill a master vampire in my quest log. When I went to the spot the vampire was at, the quest marker was hovering over a blank spot. Now essentially I can't do anymore dawnguard radiant quests. Anyone know a fix?
