So I completed my first review task today (I have never seen a single thing in the review tab for the entirety of my time here, which is 4 years), but I didn't get the badge.
Is it possible that someone else finished the same task before I could finish reading the post, editing the post, and checking for duplicates?
Never mind. The badge award system appears to have some kind of delay, I have the badge now.
There might be a few other places like this in the Help Center that could do with some touchups. Would it be helpful to compile such a list in a Meta post, so that the mods can fix them when they get the time?
