Beloved by the Undead, Hated by the Guards

[Sacremas]

Okay for some reason Vampires just totally dig my Werewolf. Every vampire cave and ruin I enter all vampires and their thralls in there are friendly, even if Gargoyles jump out of the wall and attack me they just don't care. I can even murder their friends infront of them and they never turn hostile until I attack them personally. This is regardless if I'm in werewolf or human (nord) form. Note that it's only vampires, bandits, draugers and so on still attack me as normal.

 

On the other hand entirely at random intervals guards when I'm in human form tend to go berserk on me, and not all the guards, just individual guards that I pass by who then jump out and attack me, get their heads cut off, and then their fellow guards who was watching the thing wander over to the body and go "I'm going to get whoever did this!" despite standing just a few feet away observing the fight, and I never get a bounty from killing these (I do get a bounty if I attack the other guards). I've been telling myself they're dark brotherhood assassins in disguise. (No I don't have any mods that actually adds disguised assassins or the like.) Additionally Militia patrols (not sure where they're from, either Immersive Patrols or ERSO - Erikel Real Skyrim Overhal) almost always attack me on sight, first time was almost comical, we were heading to the western watctower to kill Mirmulniir and the Whiterun militia went hostile on the entire group (me, Irileth and the guards) and killed all of us. Epic fail. Note that I was already a werewolf at this point in case it's related.

 

Also twice now on the same save I've had NPCs go berserk on me for no reason at all, once I entered Dragonsreach and the Jarl was hostile, second time some 20 levels later I entered the Bannered Mare and Uthgerdt and Delphine (there after Dragon Rising before returning to Riverwood) went crazy... and got murdered by a mr Sam Guenevene who apparently really really want to get me drunk and play with his staff, not sure I trust that guy... Both times it was solved by reloading outside, waiting a couple of days then returning and everyone had forgiven me.

 

Anyone have any idea how this came to be, or how to fix it? I'm a werewolf as said, I don't have a bounty (none except companions have seen me shift), and I'm using Moonlight Tales latest version to make wolves and werewolves friendly to me. That may have caused the vampires to get friendly as well if they're in the same faction (Vampires often have wolves in their lairs), but I have no idea what's up with the guards and random NPCs freaking out on me. I'm using Perkus Maximus but I'm not using Masquerade or any faction armors, but I was able to use it's 'hug' feature in Speech to make a Vampire Nightstalker random NPC a follower since they were friendly, she's currently hanging out in Paradise Valley getting a tan... Also I'm not using any illusion spells or the like that could change factions, I'm almost pure warrior+thuum.
