SmileBasic occasionally fails to save

For some unknown reason, my copy of SmileBasic can "save" but sometimes, SOMETIMES, after a reboot, it won't load that save, but will load the previous version of that save. This one straight baffles me. I have no clue why it does that.

Could it be that you're loading the backup? (Actually, I don't know if the backup stores the previous version before saving or a copy of the currently-being-saved version. I think it should be the former.)

The backup is a backup of the file in disk before saving. For example: File "A": "Help" User edits file "A" to say "Frick" User saves "A" File "@BACKUP.PRG" says "Help" and file "A" now says "Frick"

Check if you're still in the same folder as the file you're saving. Many times I've moved over to another folder to check on some piece of code, then forgotten to move back to the original folder. Try opening the "Browse Projects" menu and sorting by date with the small button by the Back button. That'll sort the folders by most recent edited file. Check some of the folders nearby the folder that you're working in, to see if you mistakenly saved a file there. Also, you may have to check if your SD card is getting corrupted. I don't really have a way to check this, but if any files suddenly break or become unreadable, that might be the root cause of the issue.

It's not really that either, I think, because it's rather rare and pops up at seemingly random, but it is annoying.
