So I created a mod that simply copy/pasted 3 armors and 3 helmets.
Everything is almost the same except few values, like hitpoints and Projectile dmg.

Did not touch anything else.

But when we damage the armor ingame then we see that the armor/helmets skin changes after how much damaged they are.
But the colour circle and status showed something diffrent. when it got ruined it was still yellow/damaged. But ruined.

I just can't figure out what is causing this.
This sometimes prevents us from repairing because it is worn but is actually damaged or badly damaged.

The mod is Called : ArmorModTest made by Digiblast
