So, I recently found out that if you have the digital copy of New Leaf, you may have two towns on two different SD cards. But, I jumped the gun a bit by buying a SD card before looking in to it a bit more. Are there any risks at all of downloading New Leaf on to a second SD card, in the form of possibly messing up my first town? Maybe there is no way it could corrupt my first one and I am over-thinking it, but any warnings?
