The bug that you can only ban 3 maps occurs when you have still banned some maps from the previous patch that are still in the pool. So for example you banned nomad before the patch, the game remembers that ban and your red cross is still there. As long as there are banned maps from the previous patch, you can only ban 3 maps. You have to uncheck all maps the first time you start the game with the new patch. After that you can ban 4 maps as intended.So I installed game just to check if it works now. Seems I can only ban three maps, not four. Every time I try to ban fourth, one ban lifts. 11 Seems like promising start...
