Maybe a little bug, even though I think it worth to report.
In Badges section you see that Reversal Badge has 1 awarded, like bellow.
But when you click on it, there isn't any awarded. See below:
There was a bug in the job that synced these counts routinely, specifically it wouldn't fix the "now 0" case, a join vs. a left join going on. This will be fixed in the next build.
