My NANDS are unlinked, and when I go into emuNAND all of my titles just vanished, except for legit CIAs that I installed with FBI, illegit CIAs, and system titles. It happened when I tried to update YouTube on emuNAND. They don't show up under HANS or SDVT, and they can't be booted with DevMenu. But my SD card still has the same amount of free space, so they must still be on the SD card. EDIT: Fixed, just make a new backup, format emuNAND, link NNID, and restore your emuNAND backup.
