Ashtron Armour Upgrade System

If you choose the Game Start of this mod, then here you will find the requirements to upgrade your armour, since Ashtron/Ultron races cannot equip other armour than their own.

When you first start, you will respawn with a cheap quality Copper Armour Core. In order to keep upgrading this you will need to build the necessary Crafting Bench and upgrade it.
