remember folks... the ai doesnt decide anything. its not capable of making educated decisions, it's a series of hardcoded commands which uses a database to make it's random choices.

Arhus might have been taken because the English are hardcoded to land there and attack, no matter what the circumstances, in that version of the game anyway... they will eventually land there.

It doesnt give a flying dingleberry who its allies are. Thats the part thats broken.
