Archer bug ?

[Byakkotai]

When the enemy is at a certain distance and there are still targets left that are further away from my ranks they sometimes just won't shoot. You see the animation and the sound an all but nothing is being fired. Sometimes I can target the targets that are further away, but it takes a lot of clicking before they finally listen. Any ideas on how I can solve this ? Other than letting my archers move away so they can shoot again..

If you leave your archers on fire-at-will the engine will calculate friendly-fire. Take your archers off fire-at-will and target them yourself

Ah I see, thank you. But the times I left them at fire at will they often shot at my own men as well, mostly if the enemy was not close to my archers. But I guess they don't want to fire at point blank range killing many of my men.
