I play an old Civ3 COTM on a dusty computer and was at the Regent level with impending hostility at my borders. I would soon have Replacable Parts and was flush with cash, so I planned on a mass upgrade to infantry and felt secure. When I finally was able to build infantry... NO RUBBER. Nowhere on the map at all! So I started laying plans to defend somehow else and then my computer ran out of power without saving the game. When I rebooted and got back to the point were I discovered Replacable Parts there was one rubber on the continent, and in my territory. I didn't know the map was so fluid and I presumed the resources and luxuries were set in stone. Does anyone know about this?
