I recently down-voted this off topic question: https://codegolf.stackexchange.com/questions/132940/chess-championship Why was I not awarded the badge "critic" within the next minute? It seemed to work almost instantly on other SE sites.
Badges are handed out in batches throughout the day, different batch jobs handle different badge types.
Source: When are badge calculations done? on mother meta.
You must have been lucky on other sites.
I note that you do have the badge, awarded about half an hour after posting this question, so as a support issue I think it is resolved.
