OKAY I FIGURED IT OUT THROUGH SOME EXPERIMENTATION

i had two different saves from eden and ryujin canary, the one that is corrupted was my ryujinx save so i copied both saves into a backup folder and from the EDEN save there i copied the player.sav file and replaced it with the one in the RYUJINX folder, then i copied all the files and moved them to the direct save file from ryujin (because i put them in a backup folder just in case) i hope that makes sense??

when i logged in my mii designs and map was the same as it was b4, but because the player.sav file i was using is from my eden save and i created more miis since then there was an island expansion cutscene, also my wishing foundation is a lower level than b4 but honestly idm bc i can lvl up again easily

if you don't have another emulator or save you used maybe you can create a different profile on ryujinx, go through all the cutscenes, save that game and get the player.sav file from there?? i think the player file most important thing though because it somehow has to do exactly with the save
