When I click on the review queue, often there are items in two categories to review. When I finish one queue, however, and click on "view all review queues", the list then comes up empty for all queues. It doesn't matter which queues they are, or what I click on to return to the queues.
At first I thought there was someone else checking the queue at the same time. Now I doubt that's what's happening.
It doesn't happen on any other sites I'm active on.
Is this a bug? Has anyone else experienced this?
