Negative durability Problem

Summary

i'm using mc1.16.2 mythicmobs 4.11.0 dev artifacts latest build

so when i try to add more than original item durability, for example 175 chainmail helmet as 1000 durability it is showing as -825/175 and armor crash by 1 hit

Steps to reproduce

this is one of -durability item. https://pastebin.com/gsMUTXJ9

Current behavior

whatever i try to set more than basic durability it goes negative value

Intended correct behavior

durability should be set as what i wrote at lore line or durability line. for example if i set as durability 1000 it should be 1000/1000 not -???/1000

Proposed fixes

i hope this durability option fixed soon, because setting variable durability option will make more option to make item (sorry about my english)
