Due to the ongoing migration of posts to prog.se, some people would have badges which are no longer valid on SO.
Example - my profile has a Silver
Good answer badge which moved to prog.se, so when you click on the badge it seems broken
(post deleted or otherwise unavailable)
I know badges will get calculated at the next point of awarding, but if lots of questions are getting deleted or migrated, is now a good time for a one-off recalc on certain badges like those awarded multiple times to Good/Nice Questions/Answers/Comments?
Another example is this guy's Tumbleweed I posed a question about earlier.
I dont think this will affect the league toppers (Pascal's been missing for a while, but earns badges each week), but will clean up a majority of those in the middle and bottom.
