I purchased the DLC for Fire Emblem Fates prior to a system transfer on my Pokemon 20th n3DS but I did not registed an NNID to my n3DS. I was able to purchase the DLC while in-game.
After doing a system transfer(since I finally got a large enough microSD card), I noticed that my DLC is now gone completely. When I go to purchase DLC from in-game, it says that I have to re-purchase everything all over again.
Is there something to be done about recovering my DLC?
