I come back to cataclysm to my save from two weeks ago. And I have huge problem. I come back to my faction camp and all my “friend” NPC’s, goes agresive and attack me. I use debug menu to spawn more NPC’s and still they are ok when spawn, and after they start following me, the immediately goes agressive. Can bionics do stuff like this? Or is it bug?
You probably offended members of the Your Followers faction and they have an extremely negative opinion of you. Hence their desire to kill you.
