[Unknown Mod][Castles] Additional Archer is added to the strength of the Ballista for the castle defense for each upgraded building

[LeHerosInconnu]

With this option enabled, 1 additional Archer is added to the strength of the Ballista (and therefore for turrets too) for the castle defense for each upgraded building.

In the original game, 1 additional Archer is added to the strength of the Ballista for the castle defense for each building built (Ex: Archery Range, but not for Upg. Archery Range).
With this option enabled, 1 additional Archer is also added to the strength of the Ballista for the castle defense for each upgraded building (Ex: also for Upg. Archery Range).

This is an option:
"Battle: Additional Archer is added to the strength of the Ballista for the castle defense for each upgraded building"

Edit.
This is also the case for each level of the Mage Guild in addition to the bonus to the Attack skill.
