Game I got years ago requires another purchase

Are you using the same account in which you bought the game? (also, this problem happened with me, i used to have Tomb Raider Definitive Edition, and it is gone, now i need to pay again, i love physical media)

Hi SammieChaos

If there is no record of purchase on either account for this game, then, unfortunately, the game was never purchased by either account. Your Microsoft Account order history is an accurate record of all the purchases you make on your account so that there
is proper documentation after every transaction.

Slime Rancher was available in August 2017 as part of the Xbox Live Games with Gold program, allowing Gold users to download and
play this game for free as long as you were subscribed to Xbox Live Gold. This is likely how you have achievements and the game can be installed on the home console as it seems the other account likely got this game during that period of when it was free with
Gold.

Either way, we cannot assist further regarding license or ownership issues since we don't have the tools to look into your account if all the troubleshooting has been done. I suggest contacting Xbox customer support as mentioned above. Here are the best
steps to reach a live agent:

1. https://beta.support.xbox.com/contact-us.
2. Select Contact Us.
3. Select "Subscriptions & billing" in the first drop-down and then "I can't redeem a code" in the second drop-down
4. If you are not logged in, you will be prompted to log in to your Microsoft Account at this point.
5. Once logged in, scroll down in the window to Other options and select Request a Call.
6. You can add additional information at this point if you'd like and then select Request call
7. A new window will open for you to enter your Country/region and your best contact number, then select Confirm and you'll be placed in a queue to receive a call back from Customer Support

My profile is set as home for him.

As soon as I remove my profile from home all the games including Slime Rancher disappear from the Xbox.

His account is much newer than mine he didn’t even have the account in 2017.

However, I’ve checked the purchase history under both accounts and there isn’t anything there for slime rancher on either account.

Yet i have achievements for the game and history that shows ive had the game before.

Yes I’m using the same account.
