There is a check in the matchmaker queue that is supposed to never happen, but I'm seeing some messages in the logs that it is happening which means there is an issue with the state tracking that's allowing players who still have a search in a queue to do other things on the server.

Here, this player remained in the queue for over 4 hours and kept being matched with other players which then caused those other players to never find a real match. There are many messages but here are just a few to look at:
