I just wanted to let you all know that the Krokosphinx Delver badge is bugged and that Wizard 101 knows about it and is working to correct it. If you had the badge before the latest update, you'll notice it's no longer on your list now. Also, if you were questing for this badge and weren't able to complete it, it's no longer an available quest. I don't know if it's available to those who have not yet started it, though. Just an FYI.
