Hello, my 9 year old son has a 3DS & 3DSXL. He loves Terraria and has been playing for awhile. He must have hundreds of hours logged. He says he just entered "expert mode". That said, a few days after entering expert mode every time he tried to start the game with his file the save file would not load and the game would crash. I tried to update the game but, that didn't work. Then realized it was this particular save file when another save file opened just fine. So then I tried to find a back up file but, his system says he has no backups. Not sure why. Anyway, is there some other way to save his file?? He is distraught over losing all his progress.
