Game freeze in Asia Minor river crossing battlemap - impossible pathfinding likely

Hi guys.
It appears there is problem with battle map on the river crossing one square to the east three squares to the north from city of Ipsos, in particular that battlemap is generated in a way that game freezes on start battle button when there is reinforcing army nearby(maybe just in one particular square, maybe in multiple), same way like here https://forums.totalwar.org/vb/showt...13#post1712313
In the battle I(AS) was defender, AI(Pontos) was attacker with two stacks, likely each one from different riverside.
Savegame from end of turn is here:

Problem is that AI does not act the same way after loading the game and won't attack there any longer so it might be necessary to arrange a battle there to verify. I don't recall which square they were attacking from.
If I saw it correctly, the primary attacking army spawned up on the same side of river as I did(second never shown), and first guess is that problem was that there is river turning north on the next square to the left, so this might have been the issue. Also there was no bridge/crossing on the battlemap but I can't guarantee this.

Thanks for the report, unfortunately I was unable to get the AI to do the right thing :no:.
