Corsair Cove advertises Steam Cloud, but Cloud synchronization is not a replacement for deliberate in-game saves. Keep named checkpoints before major Compass spending, camp or pier expansion, expensive ships, risky events, and story decisions. When switching devices, let Steam finish uploading and downloading before opening the game on the other system.
Build a useful save rotation
Keep at least three roles: a stable-island save, a before-decision save, and a recent-progress save. Name them by purpose, such as “before Trade Pier” or “before Tides event,” rather than overwriting one file repeatedly. This makes a rollback understandable days later.
Save while the island is connected and essential upkeep is stable. A checkpoint made during a hidden Stew collapse may restore successfully but still contain an economic emergency.
Confirm Cloud state before switching devices
Exit through the game’s normal menu and wait for Steam to show synchronization complete. On the second Windows PC or Steam Deck, connect to the network, open the library, and wait for the Cloud status to settle before launching. After loading, check the save name and in-game date or progression state.
Do not launch both devices into the same save simultaneously. Each can create a newer file, forcing a conflict where timestamp alone may not reveal the state you want.
Handle a Steam Cloud conflict
When Steam presents two versions, stop and identify which device last had the intended progress. Compare displayed timestamps, device, and any available file details. If unsure, cancel rather than choosing quickly. Preserve the local state through supported Steam or game controls before resolving.
After selecting a version, launch once, verify the island, create a new manual save with a distinct name, exit normally, and wait for synchronization. This creates a clear post-conflict checkpoint.
Do not use an unverified generic save path
No reliable current official source was found for the exact Corsair Cove Windows save or configuration directory. Many games share engines or folder conventions, but copying an Unreal Engine path from another title does not prove it belongs to AppID 1368140. Proton paths add another application and user-prefix layer.
This guide therefore does not instruct you to edit, rename, or delete files in a guessed directory. If the developer or publisher publishes an exact path for version 1.0, verify the AppID, platform, and date before using it.
Prepare a safe device transfer
Steam Cloud is the advertised transfer mechanism between Steam installations. Before moving from Windows to Deck or back, create a named save, exit, confirm sync, and open that save on the destination. Keep the source device offline from the game until the destination has loaded and resaved successfully.
Steam Deck runs the Windows build through Proton; Cloud support does not imply native Linux save-format documentation. Avoid manually copying an entire compatibility prefix as a first response.
Recover from a missing save list
Confirm you launched the full base game, AppID 1368140, under the correct Steam account. The Demo is AppID 3858730 and should not be assumed to share or transfer saves. Check the library Cloud status and network connection, then restart Steam before changing files.
If the list is still missing, do not create many new saves with the same names. Record the last device used, last successful save time, whether Steam showed a conflict, and whether the game or client updated. Contact official support with that evidence.
Protect progress before troubleshooting
Do not disable Cloud, clear application data, reinstall Steam, or delete an unknown folder while the only copy of a save may be local. File verification checks installed game content and should not normally be treated as a save-deletion tool, but preserve your manual checkpoints and Cloud state before any larger action.
For crashes, record whether the failure occurs during manual save, autosave, loading, or ordinary play. Save-time crashes are a narrower signature and should be reported separately from random gameplay crashes.
What Steam Cloud does and does not prove
The store feature confirms that Corsair Cove integrates Steam Cloud. It does not publicly establish the exact files synchronized, conflict-resolution logic, number of slots, demo transfer, or cross-store transfer. Epic and Steam use different platform services; no cross-store save parity is claimed here.
