AI not dealing damage to armor

Hello i'm having a bit of an issue and can not for the life of me figure it out...

Ive tested on a brand new fresh server & also my server that ive been setting up with plugins and the problem still remains so im guessing there is a cvar or something i am missing thats causing the issue.

AI do not deal any damage to armor equiped on a person
in PVP combat i will take damage to the armor that is equiped, does anybody know if this is a feature of the game? Or if im just missing something.

As far as I know, only player based dmg reduce the armor durability. I created a plugin for the npc damage the Equipped items. Soon I will put this plugin here, until that, if you want to try it out, contact me on discord: Kaucsenta#8175
