Hacking white 2 keeps saving

[Zioplys]

pretty much as title says, i went to save and the game doesnt complete saving, bar on the bottom screen is full but it doesnt complete saving
had a 40+ hour savefile corrupted before and am quite scared to lose another 30+ one
what can i do?
M3I Zero with sakura btw

i turned the game off and on again and luckily got back to my previous save point, but this was still one of the weirdest things that happened with my M3, glad I got it resolved

It is always good practice to make periodic backups of any important save files, it's a good idea to store these save files somewhere safe, and it's a good idea to keep old versions.

As for the issue, you might want to reformat your SD card as FAT32 with 32KB cluster sizes,
