JKSV turs my save backups into empty, extension-less files

[DinnerBug]

I recently had to reset my custom firmware and rebuild the partition based emuMMC. Backed up everything with JKSV before resetting.

Now when i try to restore the saves, it doesn't do anything. I noticed that after transferring the save files and opening JKSV, the save folders got turned into extension-less files that are 0b big and with the same name as the folder or file they replaced.

This "transformation" only happens to files created before the reset. If I make a backup with this installation of JKSV it behaves normally.

I apologize but for some reason I can't see the page that the first link in the comment leads to.
I formatted my sd card to fat32 utilizing Hekate's built in tool so I did that and carried on with H2testw. If H2testw returns a bad result does it mean the sd card is bad and needs to be replaced?

Exactly that does means.

Don't worry is exactly that what the post on GBATemp says.

The test I ran on the micro SD card returned with no errors

It appears my NAND had gotten corrupted. This would explain why remaking just the emuMMC would not fix the issue. A NAND restore fixed the issue.
