I changed the “Rank Rotation”. Now the unit can move but very slowly: so it isn’t advisable to use this ability during the change of position of the unity (this was not used during movements), but this is not an obstacle during melee combat (how it was when it could not move).

With “Roman Formation” enabled, the unit moves forward with it in operation and protects itself until it engages the opponent and fights melee, keeping formation for the entire combat.
During the fight, formation can be repeatedly enabled and disabled.

With the "Centuria Formation", the unit moves forward with it in operation and protects itself until it enters the "ray of attack"; here the unit resumes its basic form and charges (if it has it, it also launches the pilum). When the unit fights the "Centuria Formation" in close combat, it can be reactivated and deactivated several times. When the unit has Centurian Formation active and is attacked, it will keep it during combat.

With the "Shield Wall" active, the unit can't move, but when engaged by the enemy in combat it maintains active formation (obviously it lowers the shields to fight melee). Once the combat is over, they can be repositioned into formation by reactivating the command.
During the fight, formation can be repeatedly enabled and disabled.

Fixed some effects of formations: “Rank Rotation” and “Pilum Effect”

Rank Rotation:
Historically, the Roman legions adopted this strategy that allowed, during a melee combat, to have in the front line, soldiers always fresh and rested.
In game, this capacity is simulated by the "Rank Rotation" function that needs to be manually enabled and disabled.
This ability reduces fatigue and increases morale; but being historically employed when soldiers are in neat formation and not scattered, it is not possible to move the unit until the ability is active. When you turn it off you will be able to move the unit again.

Pilum Effect:
The pilum was a technologically advanced weapon for its era in which it was used.
It had been conceived with a particular conformation that once thrown, remained hooked to the shields of the enemy, often forcing them to do without it in the next melee fight. Also unlike the classic spears, the pilum breaking was impossible to be picked up and reused against the same Romans.
For these reasons a pilum discharge caused great damage and confusion in enemy ranks; the Roman charge happened immediately afterwards to maximize the disorientation of the enemy and inflict huge losses on him.
Now with this update, in the game, the launch of the pilum actually has a concrete effect on the enemy, with penalties on his morale and various aspects of his defense, such as shield and armor.
