I've just been awarded the revival badge for this answer.
I didn't deserve the badge according to its description, which reads:
Answered more than 30 days later as first answer scoring 2 or more. This badge can be awarded multiple times.
My answer was not the first answer to score two upvotes. The accepted answer earned two upvotes before my answer.
Today, as I took another look at the question, I realised that the accepted answer was in fact wrong, so I downvoted it, reducing its score to one. This left my answer as the only answer currently having two or points, and I was then awarded the badge.
Is this behavior intended? If so, then the description of the badge might need reworking.
