[ZAMBIEICENINJA3]

• Construct's Armory: conarm-1.12.2-1.2.5.10.jar
• Tinkers' Construct: TConstruct-1.12.2-2.13.0.183.jar
• Mantle: Mantle-1.12-1.3.3.55.jar
• Forge: 14.23.5.2860
  Observed Behavior: most armor polishes and constructs armory pieces have a armor toughness of 0 when they shouldn't
  Expected Behavior: they should have a toughness based on the material used
  Steps to Reproduce: i have a very large modpack of 200+ mods so im not sure how to reproduce this bug, i can send my logs and mod list if needed

The base armor pieces made in a crafting table have their intended armor toughness, however most armor and polishing kits made using constructs armory do not have their intended toughness value
