My daughter has a 3DS and recently downloaded and purchased AC: Happy Home Designer. She played it for a few days and her data become corrupt. She lost a lot of progress and deleted the save data and started over. She was pretty disappointed but I encouraged her to try again. Once again though, the data has become corrupt. You can see a picture of the DS error here: http://imgur.com/G7JT90B
I have not chosen to delete the data yet because I'm hoping there's a way to keep from losing it. She has MANY games on her 3DS XL both in digital and cartridge formats but I can honestly say she's never had any data probles like this with other games. I'm hoping someone can help me as I've been trying to find a solution online but nothing is coming up. Thanks!
