oops. Missed that. To clear your cache on the XB1, just power the console down. then unplug the power source FROM THE BACK OF THE CONSOLE. It wont work if you unplug at the wall because your the brick in the cord has a back up battery. Leave the power cord out for about 25 seconds and then plug it back in. restart the console.
You will get a green screen and then it will load. this means that your cache (Buffer) memory has been cleared. I am not sure that will solve your problem but it might. Let me know what happens.
well, that makes it sound like it is a console problem and not a game problem. You could do a google search and see if others have experienced the same thing. Maybe a problem with the disc reader in the console.
