Before changing anything
- Exit the game and let Steam finish synchronization.
- Make a copy of the existing save area before moving, renaming, or replacing files.
- Keep the original folder structure and timestamps in your copy.
- Check the latest official announcement for a save-specific fix.
- If recovery is still needed, report the case through official support with logs rather than testing random downloadable ‘save fixers.’
What AG-12 changed
The new automatic backup system is designed to preserve previous saves after an unexpected interruption. It is a resilience feature, not a guarantee against every corruption scenario, sync conflict, manual deletion, or incompatible old build.
Steam Cloud
The Steam store lists Steam Cloud support. Cloud synchronization and the game's own automatic backups solve different problems: Cloud moves/synchronizes data; backups preserve earlier local states. A sync conflict can still require careful choice.
What remains unpublished
- The number of backup generations.
- The retention period.
- The exact naming and backup subfolder on every configuration.
- A developer-approved manual restoration procedure for every failure mode.
