Okay so, I preordered and payed off the Digital Deluxe on my series X and up until today it was in my library. I go to get on my xbox today, and my Game disappeared and on my home screen it shows it as the game pass version. i go into the store and check it and it says i own the game already. is this something in the xbox store? because im really trying to play this game on the 16th.
