Incompatible Save Version

This is caused by the system reading DLC in the save data that it no longer recognizes in your system. There are two known causes:

• You either previously owned the DLC and no longer do or were game-sharing with an account/console that has DLC that you don’t.
• Workaround: The only fix here is to either start a new save or (re)acquire the missing DLC.

• The connection between your entitlements and servers isn’t syncing correctly. 
• Workaround: While this has been known to clear up on its own, try completely powering down your console/PC, waiting 30 seconds, and then booting back up. This ensures that the connection on both ends has been restarted.
