Check the file first
Create a new manual save in Stellaris, then locate it using the platform save paths. Confirm that the file has a .sav extension and a recent modified time.
In the Companion
- Refresh the campaign list.
- Use manual import and choose the file directly.
- Grant folder access if macOS, Windows, or a sandboxed package asks.
- Wait for ingestion to finish before importing the same file again.
If parsing fails
A new Stellaris patch, a total-conversion mod, a damaged save, or an unusual archive format can expose data the parser does not yet handle. Keep the original file, record the game version and mod list, and submit a feedback report.
