The Attack Screen will not let my army attack an adjacent city, although it has no protection and has a 'send campaign' button available. It says it can't find a city or army despite having the target clearly identified and my selected army also. The 'name of army' section does not have a drop down button from which to select the army I want to use. It does not recognise the names I write in after splitting and re-naming my forces. It insists on coming up with 'Army 3' or whatever was the last army created. This is most wearisome and frustrating. What should I do?
