Are you expecting to be able to walk straight through enemy forts?
We're never gonna get rid of every possible weird path caused by ZOC because if we did then forts would have to no longer block movement. You're trying to get all the way around an enemy fort, that is gonna cause some circuitous paths.
Oh come on wiz.
Usually I find you funny when you're being a douche.
This time however, there's literally no reason for it.
There is no defensible reason for that pathing. It's horrible, and if done manually could be shortened significantly.
Kazan -> Vetluga makes sense and would be a possible move if done manually.
That might even be where the army came from originally.
A 3 province detour can be quite a big deal, especially when fighting on several fronts.
That sort of shitty pathing can make you lose wars, especially on higher difficulties or in MP.
It's bad, and you should admit as much. Even a simple. "Yeah that sucks, but I haven't found a way to solve it." would be nice.
Or is this one of those problems that's going to be deemed a feature and ignored?
