Going to clarify the cavalry bug. I've tried to redownload and repatch now too, so I'm sure it isn't only I who has this problem.
When you tell cavalry to directly charge at the start of a battle, without leading them into combat, they just stop and stand still. They won't even bother if they are so being swung at. The only workaround is to tell them to follow you, lead them right into a infantry horde. I guess it's when their horses deal charge damage, they for some reason go back to normal. That said, cavalry can not deal charge damage against other cavalry. Making it impossible to fight mountain bandits and such. As they simply refuse to do anything. I guess I'll have to wait to get a templar / expert rhodok condottieri army... :/
