What the f**king f**k is up with the Silver-Bloods and Vigilant Tyranus in Markarth?!

[A Harmless Burke]

I walked out of Understone Keep in Markarth, and all of the sudden Vigilant Tyranus starts attacking me! I disabled his AI and walked into the Treasury House to obtain the Stone of Barenziah, and then the ENTIRE Silver-Blood family ATTACKED me! I quickly picked the lock to the room in which the stone was, grabbed it, and ran out of the city. I had to run all the way to the orc stronghold in the Reach before I got them all off my tail. What the hell do I do?!

Check your Active Effects to make sure you are not becoming a vampire. Check you game Settings under Crime to make sure you do not have a bounty on your head.

Do you have by any chance the combination Obis 2.01 and immersive patrols 2.0.3? It's a common problem between those 2 have forwarded it to the mod author of immersive patrols and lots of obis users with immersive patrols have problems with random aggressive behaviour
