I am playing a game as the English on High with the BKB mod, and I have conquered Aragon, the Genoese and the Venitians, plus taking Toulouse and Burgundy when they went rebel. I was at war with Hungary when the Danes sent their troops across the North Sea and landed in Mercia and Scotland, as I did not have any ships in the North Sea. They then proceeded to send their enormous fleet to annihilate mine, which they duly succeeded. This I can understand. I sent mercenaries over from Ireland to retake the lost provinces and trained some more troops to guards my shores. The Danes had not been excommunicated for attacking my ships, yet when I built one and unsuccesfully attacked a Danish ship, I got a message from the Pope telling my that if I did not cease hostilities with the Danes, I'd be excommunicated! The cheek of it! Then I had a few ships in the Med, off Sicily and in the Ionian sea. Yet the Byzantines still managed to land an Army in Toulouse. This frustrates me enormously! It's one rule for it and another for me!
