when I was in the commonwealth/wasteland, I remember killing settlers but not gaining exp, but I shrugged it off thinking maybe the exp lagged/glitched and just didn't show up (or i flat out didn't notice it). But now I'm in vault 81, and I remember one of the fun things to do in NV was grabbing my silenced pistol and picking off random residents for some extra exp. But in this game, I don't seem to be getting any exp. Is this an intentional change, or is my game glitched?
