Failed saving of game data.

Power cycle the console, once the console is back on clear the DVD/BluRay cache as well.

Hi there,

please try the manual power cycle steps like mentioned on the following link, be sure to wait at least 60 seconds before powering on again:

http://support.xbox.com/en-us/xbox-one/console/power-cycle-console

If that fails, please check how much storage space is available on the console.

Let us know the results

Dont save it then try to resave and see what happens.

If the problem persists, you can also do a factory hard reset while keeping the data on the Xbox

Hi,

Power cycle will be the only way to solve your issue.

If still happening , delete the saves game (only on your Xbox NOT the one from the cloud).

Launch the game and you should be able to download the one from the cloud.

Regards
