Good thing you got the game going.
Since scenariomode is new since in beta5 I hope you will take some extra consideration to the bugs.
The normal gamemode has evolved for four versions already so that one is a bit more stable
Anyway, if/when you face an error/bug, please do not quit the game but report it here, then we can investigate the data and hopefully find & fix the bug quicker. If the game is ended, it will be automatically cleaned out after a while, and much harder to track bugs...
Thanks!
