Can't unlock activity achievements :'(

[Fry750]

I've completed Escort, Drug Trafficking, Demo derby and not one of them handed out an achievement, i loaded an earlier save and did the demo derby and it worked i really can't be arsed to do them all again unless there isn't a a solution, has anyone else had this problem???

Only reason I can think of you not getting the achievements it the possibility that you or someone else that's played the game with your game save could have used one of the cheats that disables them and saved, without realizing it.

Did you complete ALL escort an drug traffic missions or just one of them? There is one for each gang for each activity.

I've done all three but i did do the Wrath of God cheat but i thought when you turned your xbox off it turned the cheat off, the other achievements work fine though

did you save the game after putting in the cheat? if i understand correctly, if you did youll not be able to get achievements after that, with that character (unless you have a save from before you cheated)
IF you saved that is.
