Ok, so i got this weird problem today. I had just begun the questline for the Stormcloaks, and at the point where i had to blackmail someone in Markarth, i naturally travelled there. What happened is that every guard attacked me, not the other people (vendors, miners etc.), only the guards. Well, the normal townsfolk, and jarls, and basically every non-guard NPC attacked the guards. The same happened in Morthal, and Solitude. I managed to kill of all the guards in Markarth, and everything was back to normal...mostly, just normal without guards. And as the title said, there was no bounty at all, and these unprovoked attacks began on the first visit to these 3 holds (Markath, Morthal and Solitude). I did try to steal something and submit, going back a few saves (unfortunately not old enough or too old). And now i need to deliver a letter to someone who's bloodlust is greater than a mad Nord... So any souls out there with a solution?
