So I was on my way to complete all achievements in the game. I saved and exited the game and the next time I loaded in all of a sudden my 3ds crashed. I thought it was just a simple error until I realized all other worlds loaded fine except the world where I made all my progress. It is REALLY (AND I MEAN REALLY) important for me to play this world as im just 8 achievements away from completing every 59 of them so can anyone please help me recover my world please.
