Already many have gone several dozen turns into the game. Lots of things have been discovered. Some of you have already seen or are now figuring it out. Oh, well. I have had some great battles. It seems sieges are not at all changes, armies just stand there.
Was the passive siege AI on a new campaign after the patch, or a saved campaign game?

I know I've seen posts here indicating the patch works on saved campaigns, but I'm wondering if all the critical fixes are in place. Testing the new patch should probably be done on custom battles or new campaign, just to be sure.
