Couple of hours ago, I was awarded the Excavator badge on Meta:
Now, looking at my profile, the badge is no longer there. Heck, even the badges page says no one has been awarded. Was it revoked?
There was a bug in the awarding of these badges, as part of fixing that we nuked the badges (since they were brand new anyway)...they'll be re-granted as the badge runs on each site (this may take a while).
