I got my copy of conquest with a birthright code back in 2016 and for the longest time until last year, I did not have the special edition cartridge. I bought a preowned special edition copy of fates and my first move was booting it up on my hacked 3ds for fun and there was some data. Then I boot it on my main 3ds and I see some of my saves but not all of them. I then boot up my conquest cartridge to save my main save for it in the extra data and when I put the special cart back in, my conquest data is there. The problem I have tho is that none of my supports are in the records hall on a different file. In my birthright data I copied, I married Sakura but the S support is not in the records hall at all but somehow I have an S support with Rinkah. TLDR, my special copy of fates did not carry over my data from conquest or birthright despite it being extra data and I need help.
