So far, the maps that need to be removed are castle and evil house (due to crashing the server), shipment (due to insane lag issues), and sky fall (due to fail zombie spawning. Map cannot progress)
Bridge should be removed too unless there is a way to get visible zombies

Almost every game when I'm medic my money gets stuck at some point in the game and i can spend on pretty much everything
