I killed ranger Ranger Andy because I accidentally stole from him when I was trying to bring the dialogue options in order to ask him about Boone's wife. He chased me out of Novac and kept shooting at me. I got annoyed and finally just shot him.
Now, everywhere I go, NCR rangers spawn near me and try to kill my companion (Boone) and I... How do I redeem myself with the rangers? Or how do I at least get them to stop spawning everywhere I go?
