Hm, about pathfinding... When you post problem about pathfinding, I must say that I noticed pretty much same problem, with saving games... When I save game, expecially quick saving, after that, my mortars (and other weapons too) are so weak, cant kill even with almost direct hit in trenches... After closing game, completely, and reopening, that "weakeness" is gone for some time, but after saving, all goes wrong...
