Hey dude.

Something like that, except in this case the AI attacked my "reinforcing stack" of two infantry units, driving a wedge between this stack & my main army stack (I always try & bring a reinforcing stack of foot-sloggers along when I perform a major assault!).

So the issue could be as you say when multiple stacks are involved in a battle, the casualties end up going weird.
