I just popped into the review queues and noticed that the Late Answers queue has way more answers included than I would have expected:
On digging into the queue I quickly noticed that I was seeing answers added multiple years ago.
I can't be certain but I'm pretty sure these weren't in the queue prior to the site redesign. Not sure if this is a bug with how recent answers are getting flagged, or if this is an intended change for answers that haven't gotten a certain number of reviews?
