Game save recreation
Sometimes switching Factorio versions can corrupt or mismatch a save. To recreate it cleanly:
- Use your local Factorio client to open and re-save the world in the target version, then upload that save back to the server.
- Log in to https://game.polisystems.ch (or the client area) and click Manage.

- Open File Manager.

- Delete the existing
gamesave.zip.

- Restart your server and the refreshed save should load normally.
