I am reviewing something when I accidentally press the site logo, which brings me to the front page of the site. Then I click the review button to the left of my info (avatar/rep/badge) and find that the number of the "number of review list items" is decreased by one, and the post I was reviewing no longer shows up in the rest of the queue. I think it has been automatically skipped when the review page was interrupted.
Go to a site where you have access to a review, preferably FP. Note the number and click the title First Posts to obtain the first review item. Now don't do anything and click the site logo (or simply close the page). Re-navigate to the review page (
//something.stackexchange.com/review) and you'll find the number decreased by one. If possible, you can finish the queue amd you won't find the "skipped" rev item.
