EDIT: I found a solution, after finding him (hostile) i exited the cave, waitied 3 days, then returned. Now hes freindly and speaking to me.


Okey, i got a quest to find "Florentius", i go to the mine hes in, i defeat the "Charmed Vigilants " enemies, reach the chamber were hes caged, defeat the boss, take the key, unlock the door, and hes hostile towards me? Hes also essential so i cant kill him.


Quest name: Bolstering the Ranks.
"I've been asked to find a man named Florentius in the hopes that he can assist the Dawnguard. I've learned that he was last seen helping the Vigilants of Stendarr in Ruunvald."

Objectives:
Find Florentius.

Problem:
The Npc im supposed to talk with is hostile to me.

I have tryed the following:
1. Reloading a auto save when entering the zone, and reloading a auto save when entering the cave.
2. Exiting and reentering the cave.


(God i hope this dosent have anything to do with me being a werewolf and he being a vigilant.)
