Steps To Reproduce

Move to New game -> Multiplayer -> Host
Click on "Random Map" or "Show Available scenarios"

Notes
(0003375) Tow (developer) 2013-02-12 22:56	MP mode is not supported. Still, it should be fixed. The MP was working pretty much (aside from numerous GUI glitches), however unused code in some magic way degrades over time.

(0003381) Tow (developer) 2013-02-14 15:21	Fixed in r3203.
