Invisible Save File

Hi,
I tried looking for remedies about this online, but I can't. I have a family that I have played for probably 5+ hours since Saturday, (definitely played on Saturday & Monday) updated the game yesterday and played a different save file, and now the save file I know I saved and quit out of Monday (no recorded crash) is not showing up. It says the last time that save file was saved was Thursday (wrong??). I also can see the saves in my save folder as last being saved at 9pm on Monday, but they aren't visible in game. I do play with mods (MCCC and UI), but I deleted both and this is still happening. I also tried renaming the file to see if I could get it to pull up.
