Replying to an ancient thread in case anyone still needs another solution (unfortunately the one above didn't work for me). This thread shows up first in most of my Google searching last night. Anyways, I guess i killed a Slaver inside the Pitt and now Grouse and them hate me. So nothing worked to fix it What worked for me was "resetallfactions" in console. Outcasts still love me (and give me ammo), people are kinda rude in megaton and rivet (but I am slowly enslaving them all anyways, so that's okay) and my own turret in my house attacked me, but otherwise I've had no problems. So if anyone desperately wants their slavery back, they reset all factions. Then run around and make sure it you're okay with everything. Good luck, keep slaving people!
