I'm not sure if this is correct or if it just happened randomly, but I think with cheats the achievements won't unlock. Here is what happened: I played a game and got theif. Next game I turned on a couple cheats and it wouldn't unlock any of the others. I turned off all the cheats and then the following (3rd) game those same achievements unlocked. Like I said I'm not sure if this is concrete but that's what happened to me.
