Earlier I was checking to see (on my newest game file), if a Mirrin breeding critical error was still happening. The critical error was gone, so I closed the game and went to eat dinner. When I came back to play some more just now though, all of my save files were just gone. I had all 14 slots filled with save files but now they're all empty for some reason. 
It was nothing I did. Luckily I have a save file from when I 'saved to file' but all my other ones are just gone, so I can't try to recreate the critical error. Any ideas why this happened?
EDIT: I feel stupid. I didn't realize I actually kept TITS open, so I was actually opening a second instance of TITS. Please feel free to delete this. I still seem to have my save files.
