All saved games are saved to the Xbox storage and the Xbox Cloud storage, it should pull from the cloud storage if the save is not present on the Xbox. After clearing the Local Saved Games on Xbox One, I am unable to sync data for Minecraft. I ran through all the possible solutions, but I am still unable to sync any world data. When starting the worlds, the Minecraft app will crash and return to the Xbox home; and when trying to enter the world settings, it will give one of two messages: "Could not sync your world data. Would you like to try again?" or "This world is not fully synced or has been corrupted. Try playing the world on a console where it's in a good state and try migrating it again." This has only happened when clearing the Local Xbox One Saved Games, not when clearing Local Xbox 360 Saved Games. This has also seemed to only affect world saves that are larger than 100 Megabytes (MB). All world saves under 100 MB are able to be synced and loaded correctly.
