For who is still looking for a solution: try to have your save on your usb stick, or memory unit as your xbox likes to call it. So just go trough the normal steps, when your done editing your player, save it on your usb stick, not hard drive. This worked for me, tho I have only played 1 game so far, I might run into problems later. Also in the editor I checked the ''make 999999999 SP'' option, nothing else, no fans or manually putting in a #. Maybe that made a difference, although I'm pretty sure I tried that before.
