Hmm. Having a hard time finding the Pack "minted", but I don't think I did since I don't have any Credits.
We've rephrases the dialog sentence now. Guessing you've expected it to be minted on clicking on it. To mint, you'll need 1 CREDITS or enough ETH on B3. Please refer to the post on more details.
Also, I opened a chests with crowns in it, but they don't show up in the right corner xD
Refreshing the page should show them. We'll implement an update after opening chests as well.
Edit: Make sure you'll connect an EVM address in your Settings. For example, via Metamask, Coinbase Wallet or Brave Wallet.
