Save file reverted to old save on its own.

@JamJamsArt   Is your computer a pc? It sounds like you enabled OneDrive AFTER the April save. OneDrive MOVES newer files to its own folder to be synced thus leaving the game folder as it was BEFORE you logged into OneDrive. The operating system (Windows) knows where the files are but the game thinks the saves are in the user documents game folder. I don't use OneDrive or Cloud storage - I have a nas box for local backup. Check c:\users\(your user  name)\OneDrive\Documents folder and see if you gamer files are there. If they are and you don't use OneDrive (Microsoft really wants you to) logout of OneDrive and copy the files back to the user documents game folder. Sometimes a Windows update enables OneDrive. I have OneDrive disabled with task manager startup so OneDrive doesn't run at boot. I still get a nag from my Microsoft account about OneDrive. If you have OneDrive active BEFORE you install the game you don't have the issue as Windows redirect all calls because it looks at the date of the file. HTH
