So starting from when I flagged a post until now every time I visit any SO site after a few minutes I get a few notifications (never more) stating that I have earned the Citizen Patrol badge, yet I never actually receive the badge. It's not that annoying, but it's still a bug.
The flagged post has been removed, which is why I earned the badge I suppose, but if it is any help the flagged post (which was an answer) was located here: No Man's Sky: Finding Zinc on a dead moon - without a spaceship
This was the first ever flag I have raised in Arcade SO and since then I have not posted anything or raised any more flags.
Any help would be greatly appreciated.
