i dont use either werewolf mastery or that Lfox werewolf thing and i got this problem. I am using Brahmins Better Vampires but it never did this before. I thought it was The Last Altar because after i installed that i started gettting this problem because none of the enemies would attack me in that (not even the dragontwins) so how hard is it to kill something that gets full health back because it isnt hostile towards you! I removed The Last Altar and started a new game but same thing. I even removed 3 texture mods because those were my most recent installs with the exception of last altar. btw im also having this problem with draugr and all manners of undead. I have spawned countless undead enemies around me and nothing! they arent even hostile to inigo! woops double post. Ok so anyways my advice to try fixing would be to uninstall every mod and start a completely new game. get your shackles off then start spawning undead, save it and start applying mods to find the problem because from what i have seen is that the only relation between what everyone has installed is DLC.
