Fire Emblem Fates BS

So I bought a copy of Fire Emblem Fates: Birthright months ago and I LOVED the game.

Today I bought the physical copy of Fire Emblem: Conquest, and when I got to the part of the branch of fates, it said that the Birthright data was not found. After completing the mission, I went to the my Birthright edition and checked if the Conquest path was available. Guess what, IT WASN'T THERE EITHER!!! WHAT THE HELL NINTENDO!

(At least all the DLC I bought cross saved)
