When moving units very far that have little fuel left,
(eg. moving motorized infantry seven hexes with only two fuel left) the game crashes. This happended to me on five different occasions during the campaign, sadly I have no savegame to show it.
Units that lack fuel should have their placement radius reduced adequately, like airplanes, to prevent this.
