My son who is five loves to play the Lego Star Wars game. Lately his progress on his saved games is being erased. He will get to about 30% complete and sets it back to 0% complete. He looses all the levels he has beat and the characters he purchased. We have several other games running and this is not happening to them. It happened today after I did an update on the Wii Firmware. Does anyone have any idea why this could be happening?
