Pilla error polybian cohorts

[Kut Kautus]

Hey, I got a strange error in my battles in RSII when fighting against Rome. At the beginning of a battle when the polybian cohorts are standing still, they are making the movement of throwing their pilla. But my troops are far out of range and there are no pilla going through the air. I only see them throwing it and I hear the sound of it. Anyone got the same error?

If they are out of range then the soldiers cancel the throw.
