It's some sort of bug. I had the same issue a long time ago. Try going back with a save game, however It can be an error or corrupt save. If you can't do that then whenever you want to talk with somebody: 1.Open the console and click on the NPC 2.Type in "Setdisposition [number]" ([number]=any number you want depending on your personality) 3.Close the console. However you will have to do that with every NPC in the game you want to talk to, but only once.
