So I sort of dismissed this in previous games as being a strange isolated incidents, but since it just happened with back to back different type units (crossbow and catapult) I figured I'd ask. Why can the computer fire after moving? They moved a crossbowman onto a jungle hill (no road) and he fired. Then their catapult moved 2 road spaces and fired at my city. What gives? Is this a difficulty issue (Immortal)? Or is it a special ability I can get somehow. They were Denmark and neither had any upgrades.
