I edited this post today Fixed positioning in internet explorer? on stack overflow. I was approved of the edit, so I waited a few minutes to get my Excavator badge because this answer was posted on Jan 28 '10 at 1:06, but it never came. I have read multiple articles on meta that there have been bugs with this badge, but they have been about winning it multiple times (excavator badge: one-time only, or multiple times?), or earning it then losing it (Where did my Excavator badge go?). Am I missing something here?
