Record your platform and build first, then check the official update history. Launch coverage confirms save-file, missing-item, and achievement-sync problems were reported and patched. It does not prove that every current save issue has the same fix.
A safer support checklist
- 01Write down platform and version.
Steam, iOS, or Android; include the build shown by the store or launcher.
- 02Check for the latest official update.
Launch news records fixes for save files, missing items, and achievement sync.
- 03Separate the symptom.
Is the save slot missing, is an item gone, or did the achievement fail to sync?
- 04Capture evidence before changing files.
Screenshot the slot, item state, or achievement page. Avoid overwriting the affected save.
- 05Use the official support route.
Link to the developer’s latest news or store support rather than promising an unofficial repair.
Launch issue types
- Save-file corruption or missing progress
- Missing items after launch
- Achievement synchronisation
Check the store build
Google Play reviews mention progress issues and later fixes. Mobile patch timing can differ from Steam, so do not merge platform instructions.
Save and sync questions
What launch problems were officially mentioned?
Official launch news mentioned save-file issues, missing items, and achievement synchronisation problems, followed by fixes.
Should I overwrite the affected save?
Avoid overwriting it before capturing the state and checking the current official patch/support guidance.
Are mobile fixes identical to Steam fixes?
Not necessarily. Keep the platform and store build separate when diagnosing a mobile issue.
