Creeper World 2 maps are subject to a community review process (http://knucklecracker.com/blog/index.php/2011/08/custom-maps-and-moderators/). This means that all maps are subject to a 24-hour waiting period to allow map moderators to review and vote on acceptance. Even if your map has sufficient votes, it will not be accepted and become available before the 24-hour period has elapsed.
There are a number of improvements that we might want to suggest to Virgil, but right now the system works and Virgil will probably turn his attention towards the "next great thing" in the Creeper World universe, so I ask that you all be patient with the imposed time limit. It is for your own protection, after all! :)
