OldSaveDataFix

v1.1.1·Updated 2026-03-10

Enables loading of pre-1.0 save files

About this mod Author’s original text

Did you spend too much time in the demo/early access and find out the hard way that it was all for naught? Get 👏 It 👏 Back 👏!

Converts your demo/early access saves to the new 1.0 format. There will probably be random issues, probably not the best plan to load your demo/early access saves into 1.0 but it'll work (for now). Install, install this mod, and hope nothing breaks!

Your old character saves will be moved to a SaveData\_Character\_XX-BACKUP folder with a timestamp added to the filename. Just remove the timestamp and move the file back if you want to re-import it.

Contact Nines#9378 on discord for any issues.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
