Thanks Sapi for your feedback, hopefully the modders can improve matters there.

Here's a couple more to add to the list:

62) Fix issue where due to terrain-based movement constraints on the campaign map, even neutral or allied AI armies can (accidentally?) displace your merchants off their resources.

63) Stop AI building ships in landlocked watercourses, such as the inland seas/lakes right near Jerusalem and Novgorod (and deploying untouchable, concealed armies in them).
