I was in the Grimforge and decided to attack the 2 guards that were harassing Skickpit without engaging in dialoge. When I attacked the guards, Skickpit went hostile along with the 2 guards. After killing the guards, he remained hostile. Is that working right? I would think that he shouldn't go hostile. Or at the very least, "deaggro" after killing the guards. Especially if I didn't do any damage to him.
Did you attack or 'engage in combat through dialogue"?
If you just attack without dialogue of any kind 1) congrats you are a murderhobo 2) You probably triggered a few factions to attack you.
If not, then its a bug, but I have never seen that happen and I always attack through dialogue.
