COMBAT SkillTree Buffs NOT WORKING properly

It seems that the custom NPCs are ignoring both Armor and the COMBAT SkillTree "Buffs"  - that's what a player on our servers said.
It's again a problem that players can mostly see by playing actively and checking every single % of the skill in detail. We're using BetterNPC all around the map. Can you find out more? I have no clue what's going on but we didn't change in any way these skills. They're using the default values and setup. Here's what the player said more (view the image). The normal scientist Npc's are good as he said. 

I mean I haven't changed anything on the buffs, so shouldn't be any reason from my end why they would have stopped working if they were working before.

Changed Status from Pending to Closed
