@mexxico last night I was baffled at campaign AI way of thinking. We (the hardy sturgians) were chasing some vlandian horsemen off of our lands, roughly 1200 of us and 600 of the vlandian swine, who were in their natural fleeing behavior, however, half of our adjacent lords decided to weir off and chase a pack of 8 looters instead, leading to a 600v600 clash happening literally next to them leading to heavy casualties. Why? Would it be possible to improve the AI party movement?
PS i have the savegame of this, just before it happens, and it happens all the time unless I am the one who is chasing the looters off and join the fight later.
