Is "Drufurga and Diaperga Set.zip" on the download page you can access from your library?
If the link doesn't exist, please send a DM to my X account (old Twitter) attaching an image showing the amount paid on the purchase page.
Once we have confirmed this, we will send you a download key.
We apologize for the inconvenience, but please check again.
