Your save slot is empty or your progress rolled back after a patch
Symptom
You launched the game after a patch and your slot is empty or older than it should be. Some players report losing 30 hours, 15.5 hours or 2 days. Game Pass for PC players are affected too.
Steps marked “changes files” delete, rename or overwrite something. Back up the whole save folder first.
Stop. Don't play and don't save. Quit the game, open
%USERPROFILE%\AppData\LocalLow\Team Cherry\Hollow Knight Silksong\<number>and copy the whole folder somewhere safe as a backup.Look for
user1.dattouser4.dat, plususer#.dat.bak1and theRestore_Pointsfolders. If only an older file is there, the cloud may have replaced your newer one.Turn off Steam Cloud for the game (Library, right-click the game, Properties, General) and/or restart Steam. This helped one player and didn't help another.
Restore from your manual backup, or from an in-game Auto Save (the button under the profile).changes files
Check: Your slot shows the progress you expect.
Unverified: Some players think Steam Cloud caused the Sep 2025 vanishing saves, but Team Cherry has given no official cause.
