Another (already discovered) bug:
With some of the guys I played, when they connect (someone else is hosting), most of the times the game doesn't start automatically, it shows the resolution and control changing window. Unlike the cccaster 2.1, pressing the Ok button just crashes the game.
But here is something interesting that we discovered: After the person hosting puts the port number, the options for the mode to host appear, but is better to select the option with a number key instead of Enter or Intro, it makes bigger the probabilities that the game runs automatically. The same goes for the person connecting: instead of pressing Enter or Intro in Yes or No, is better to press 1 or 2.
