If you are playing games with Cloud Saves on more than one device through the Epic Games Launcher, you may run into Cloud Save conflicts. This is usually because you have played the game offline on one machine.
If there is a conflict, you will be prompted with the following window:
If you see this pop-up, make sure that you select the correct save to avoid losing data. If you select the incorrect one, it may result in lost progress. Any progress lost is not recoverable.
NOTE: Selecting "Sign In Later" in the Epic Games Launcher and/or playing without an internet connection will keep games from syncing until you play again online and are signed into your Epic Games account. This is very likely to cause a conflict.
