Do you have two places to store your games (external HD and internal Xbox HD) ? That may be the problem !

And you can check here if there is the solution to your problem :

Hi everybody, I have a question about forza 4. I have being playing Forza 4, and I have lost all my cars, also my money that I have won so far, also all the maps that I was racing is gone. But the only thing is that all my stuff are saved in my hard drive
in my xbox 360 pro, could someone tell me how to get everything back to the way it was before please.

I'll try that the next time it happens. had a few crashes on forza since this post but not the losing sound thing. I'd say all in its happened 4-5 times. I've only ever lost sound like that in forza and it always is gone u til reboot. I play a good bunch
of other stuff too and no issues with them. I'll be interested to try the HDMI cable next to e it goes.

Forza 4.

If I remember correctly Forza 5 lost the drag tracks and it lost a hell of a lot of other features anyway.

ive lost out on shadow of mordor and forza pre ordering stuff now because of this
