The NFT minting script had a few bugs, which resulted in the wrong memo sent to the minting script.
It wasn't as much as a bug but confusion with the UI.
The problem was the mint button pulls up a dialog that includes a drop down that shows how many you want to mint and an input box if you want to send it to someone else (the idea was to do contests and giveaways so you can send blind without seeing what it is first). The problem is some people thought this was where you enter the number you want to mint.
Once I figured this was confusing people, I changed this to prevent numbers from being sent. I have tried to minimize any potential errors by prefilling the dialog with your username and other checks, but there are always other ways people look at things you may not expect.
Thanks for the details, all good!
