When I try to play ZH with 2 of my friends, we often end up with a mismatch which quits the game when halfway. This only happens when I am playing too. If I don't play, they won't have it. It usually happens when we all have giant tank armies (usually crusaders, avengers and for me laser tanks instead of crusaders), large amounts of base defenses (aka: a wall of them around the base, at the entrances double ones and some inside the base), many supply drop zones, and obviously, giant amounts of power plants to power it all.
The map is ALWAYS Twilight Flame. (we kind of, like the map)
