I've issue an immense triumph ground and air attack. The other person has only launched naval strikes. Somehow I no longer have ground and air superiority. At least they aren't listed on my war screen. I also noticed when I go to launch an airstrike, all the defenders air units are listed. I did recently just lose all my planes, so perhaps that ends air superiority? Still doesn't explain why I lost ground control though.
