Vampire Survivors is unusually helpful because the game maintains backup copies inside its saves tree, but cloud synchronization can undermine a manual reset or rollback if the wrong copy wins. SaveEditor documents both the local AppData path and Steam’s 1794680 remote file so a player can identify whether a change was made locally or restored by the launcher. The safest recovery is to preserve the whole saves/backups tree, then choose one dated SaveData copy intentionally rather than deleting folders while cloud sync is still active.
Start with the least destructive explanation
When Vampire Survivors progress appears missing, first verify the active PC location: Windows: Windows/local: %APPDATA%Vampire_Survivorssaves ; Steam cloud mirror: <Steam-folder>userdata<user-id>1794680remoteSaveData ; Epic: %APPDATA%Vampire_Survivors_EGS<user-id> ; Microsoft Store: %LOCALAPPDATA%Packagesponcle.VampireSurvivors_9pv5cyp4vwdsrSystemAppDatawgs<user-id>. Expected files/folders: SaveData.sav in the local save tree; backup copies are kept under the savesbackups structure.. Many apparent save failures are actually profile, storefront, path-redirection, or cloud-selection problems rather than damaged game data.
Preserve every surviving copy
Back up the complete saves directory including its backups subfolder before using the in-game delete/reset workflow or manually replacing SaveData.sav. Before renaming, moving, replacing, or opening candidate backups, copy them outside the live directory. Do not use the only surviving file as the test specimen for repair or editing.
Check launcher and cloud state
Storefront context: Steam, Epic Games Launcher, Microsoft Store. Epic and Microsoft Store have different roots. A Steam cloud file and local SaveData.sav may represent the same progress at different synchronization moments. Cloud notes: Steam Cloud, Epic cloud, and Xbox Cloud are documented. A sync client can reintroduce an older or newer version after a manual restore, so recovery work should keep local and cloud copies conceptually separate until the wanted progress is confirmed.
Use format and compatibility clues
The game has evolved through multiple storage layouts and storefronts. Current Windows local data uses the Vampire_Survivors saves tree while Steam cloud keeps SaveData under app ID 1794680. Cloud synchronization can immediately recreate a file you intentionally removed. Disable or resolve cloud state before testing a manual rollback so you know which copy wins. If the file exists but is ignored, compare the complete directory structure, slot/profile naming, game edition, mods/DLC, and any companion metadata. Do not assume an extension change or generic checksum tool can repair a game-specific container.
Game-specific troubleshooting
If old progress returns after deletion, check cloud sync. For a manual rollback, copy a dated backup to the live saves directory only after preserving the newest state. If a known-good backup works, preserve it and create a fresh in-game save before further experiments. If no copy works, prefer read-only inspection and source-backed game-specific tooling over repeated writes.
