Ouch man, I had issue like that too, even worse since I couldn't make any money because I had half a content without rivers, seriously you got to come up with backup plans when doesn't turn out the way you wish, you basically got to be prepared for anything. Better luck next game, btw did you know its a sign that you are a good player when the game gives you crap.
Besides you may make up for it with shear numbers and artillery. I am very good at this game without oil because I rarely use tanks, I just find that they get blown up to easily with a good few infantry units.
