Ok, so I'm on the Prophet quest to rescue a Moth Priest. But the minute I free him from the barrier prison he attacks Serana and I (Note:I chose NOT to become a vampire). Once I "defeated?" him, I talk to him and so I leave to return to the Dawnguard hideout. As soon as I leave tha cave the Priest is there and begins to attack again. I try to beat him again and then fast travel to the hideout. Once inside the priest is there and all the NPCs begin to attack him. Once he's weakened I try to talk to him. After reading the Elder Scroll I have to talk to him, however this is where I'm lost. You can't talk to him becuase it says he's busy. I try reloading the saved point but it still happens. I'm not very tech savvy with bug glitches but I was wondering if this has ever happened to anyone else yet. If you have any information on how I might be able to restore this in-game w/ the console commands please do not hesitate to let me know.
