Re-purchase MCC (on Xbox)?

I just browsing new XGP games on Xbox and it showed me an offer to buy the game. I am pretty sure I bought this game in 2017 (I even unlocked some achievements before the XGP launched) but I checked my order history and there are no record of MCC. I am worrying if they took back my game or something. Is this related to the new version of the game since Reach is coming? Am I the only person have this issue?

Be sure you are on the account that made the purchase. Then go to my games/apps, then go over to ready to install and every game you bought and uninstalled should be there to reinstall.

It showed. Thanks man.

Glad to see you got your issue solved OP, feel free to open another topic if you still need help with anything
