When looking through questions today, I noticed the following user has only 382 rep, but a gold badge, which is unusual to say the least:
Looking at his user page shows that something funny is up. He has a gold "Great Answer" badge, but the highest-voted answer of his shown on the page has only 13 upvotes. Is this a bug? Or did he have a highly-upvoted answer that was later deleted? If so, shouldn't the badge have been rescinded?
