||unity-dev|| Bug? Unity wasn't reporting all the created rooms. Restart fixed the problem.

Perhaps your application is different than mine then, in my case, the client
doesn't need to know a list of rooms, he knows ahead of time what room he
wants to join, and will only join a single room. If you are building say a
chat client where you'd like to show the user a list of rooms, then I can
see how this could cause a problem for you
