I was just doing some Reviews on the Fist Posts queue, and encountered this post:
This I found really unusual, as this is a one month old answer, which is even accepted and has more than 10 upvotes. It is also closed.
I checked the First Posts history and of what I can see I was the only one to review it recently. Furthermore, exploring that history of reviews I can see that on the date of posting (12/7/17) user @scaaahu successfully reviewed it.
Any reasons why this post came again on the review queue? Could this be some malfunction or bug, or has someone experienced this before?
