Bug: Sometimes play/test/test stops working.
Occasionally when you test in test play, it will get stuck on this screen no matter how many times you try and make a new tab. It is often after exiting a test match by hitting "back" instead of exiting the match properly through winning or losing (or hitting the exit button), however it is inconsistent and I am not sure it is related. I have little more information about the issue. And it is hard to reproduce.
