Launcher bug

http://i43.tinypic.com/3097p1s.jpg
After certain steps, active button which allows to actually launch game during maintenance (current one) appears. Inactive one doesn't go anywhere.
Steps to re-produce:
1. Launch launcher (duh, obviously)
2. Log in
3. Inactive Play button will appear
4. Press on World icon
5. Close Worlds info window
6. Active Play button will appear allowing you to launch game when you shouldn't be able to
Note: Only happens if worlds are up (or at least one probably)
Frequency: Every time (during this maintenance at least)
P.S. Even though it ables you to launch game, connection with lobby server obviously won't be established.
P.P.S. Another launcher bug which should be addressed.

How long is this maintenance period supposed to be?
