For some reason I don't have a button to start a new topic in Tech Support, so I've posted it here. When the game ends, both commanders are well below 1000 HP, and the killing blow is dealt by an overcharge, so clearly both ACUs are in range of each other. However, only the overcharged ACU dies and the other one survives.
Is this to do with the range of the death explosion (the OC was right on the range limit), or is it a bug? The game's only ten mins or so.
