Need help please. I have recieved the Not a Recruit anymore achievement and the Kight in White Assassination achievement but no awards. I notice my award didn't pop after the achievement I went and looked through the xbox guide menu and the awards showed the game and how many were unlocked. Except Halo 4 which showed 0 of 4 unlocked. When I clicked on it, it gave me a message like I haven't recieved any awards from any game. Even the avatar store acted like I didn't reciev any awards. I reset the xbox and it gave everything back to except the Halo 4 awards. I now have the achievement unlocked but not the awards. My son was playing with me on the same consol at the same time and he recieved his award for the Not a Recruit anymore. Somebody please help. I've already talked to Xbox support and they said there was nothing ther can do i have to come here. Any ideas on what to do?
