Me exactly this 3ds is MY LIFE so ain't BODY gonna mess with it!... Unless it's homebrew lolI'm so glad my family respects me when it comes to making my town or other games. They know I worked hard.
I can totally see how it would be extremely frustrating if someone else deleted your town. If this were the GameCube Version, it may not be as bad due to how few items there are and how limited customization is. But New Leaf has even more.
And this would be horrific for me so sorry this happened! I'll be willing, if my wife Fi is willing too, to hack whatever you need!
