I am playing at the cheiftain level and have wiped out all of my enemies except the Bablyonians hemmed up on one island in Cuba where I can not land my Cavalry from my galleons as his city occupies the whole island. I have large cities everywhere else on the world. All I want to do is destroy him him. But I can't because every time I get my bombers ready the game will lock up and say "Please Wait." Normally the computer will let me have access to units that don't have a pre-set order along a movement route or those that aren't automated. But I can't access my units? Any clues
