Why are they gone?

The people we're game shared with are still game shared with us. I know becuase I'm still playing their games without any hassle. The games are just... leaving.

If you remove your profile and add it again it might fix the issue.

This is how you remove it and add it back. Only takes a minute.

When they run out of codes they remove it as an option. The length of time it takes to add them back just depends on how long it takes them to get more codes.

There's a lot of licensing involved in a game like this - from car manufacturers, to part brand names, to music sound tracks, etc - the list goes on and on. When they make these types of games they usually negotiate a royalty with those license holders in
order to use them. The contract is usually time-limited and once that time is up - they either have to renegotiate or stop selling the product - in this case, the game's are old enough to where they just don't renew any of the licenses and stop producing it.

It sucks but that's how pretty much all sports-related games such as Forza are handled.

Edit* Didn't notice the OP was so old - same month - wrong year. - Still the answer is valid to those who may search and land here.
