Use your noggin. It's an extremely low profile and in some places completely untextured version of the map clearly being used as a CLOSED TEST to give the developers some real time feedback on the map they're creating. Surely you didn't think this was a fully released final version of the game? Surely you understand this was for testing purposes? Surely you understand the process of what you even signed up for, given the fact you had to create a test key and downloaded a separate, alpha "experimental" version of the game?
