I lost access to a majority of games I had gotten with gold, I don't know what to do.

Watch Dogs 2 nor Sea of Thieves have ever been games with gold.

It could be your system is simply re-indexing your drive, which happens from time to time, just give it time

Hi,

Usually this kind of code ships to your xbox live messages directly or to your email a few weeks after you launch and play the purchased game once on the profile. So technically you should get the code after getting Halo Wars 2.

This is how it worked with Gears of War 4 and the free first games.

Should the terms and conditions (read the fine print) of your purchase state otherwise you might need to wait a bit still as they ususally roll out codes within specific delays and it is almost never instantly after purchase.

If you still feel something is wrong, contact Microsoft store support directly from their page!

Hope it answered your questions!

Cheers

It only happens on Lego marvel Super Heroes 2

I have tried everything on the troubleshooting page. Apparently the error code it keeps showing is in reference to an Xbox360, even though it is an Xbox one. I'm confused

I have the same problem!!!
