Steam Cloud Out of Date – What It Means and How to Fix

Another related issue is:

“Steam Cloud out of date”

This message appears when your local save files are different from the ones stored in the cloud. Steam asks which version to keep.

Why This Happens:

• You played offline and made local changes
• Another PC used the same account with different saves
• Cloud failed to sync previously

Steam shows a window comparing:

• Last played time in the Steam Cloud

Choose which version to keep.

⚠️ Warning: Choosing the wrong version can overwrite your save progress.

✅ Option 2: Force Sync

If Steam fails to sync:

1. Exit Steam
2. Delete the “userdata” folder for the game (after backing it up):

   C:\Program Files (x86)\Steam\userdata\[Your SteamID]

3. Restart Steam and launch the game
4. Steam will resync the cloud data

Steam Cloud Sync Error – What to Do

You may also see:
