- removed the Norman and Norwegian invasions - this is more of a subjective change, but I don't like the way they work and don't think the game engine handles them very well; it is still fairly simple to start a claim war and conquer England as either William or Harald if you want to, as you're smarter than the AI and can use marriage alliance exploits
