I don't know if this is a bug or the way you designed the mod.
I was helping my King to lay siege to a castle, but all of the men just stood there as the archers pummeled them with arrows. They didn't run up the ladder or anything. Well, actually, one at a time did. A few soldiers went right up to the wall and stood there instead, and the rest just stood in their spawn positions with their shields raised. Then one at a time would progress up the ladder until he was killed by arrows, then another until he was killed, so on and so forth. I mean, are they waiting for me to go up the ladder or something because that's just something I cannot do until my soldiers clear the way. I'd end up "unconscious" way too fast. One other thing is that it would seem that the archers would run out of arrows because they'd periodically calm down for about 30 seconds to a minute or so, and then they'd start right back up again.
Is this what you designed this mod to do in castle sieges? I mean there must be some reason you offer the war mod separately, but I thought that was just because at the end of the quest, somehow we were unable to continue taking over Astorionar.
