Some questions about weapon upgrades

  1. When using a drawing to craft a weapon at the workbench, you find that the weapon you get shows that it has been upgraded twice. This means that you can only upgrade the weapons you make at the workbench once. Is this the original design or a bug?
  2. The first time a level 3 gear armour upgrade requires 10 silver ingots, but the next two only require 4, which doesn’t seem reasonable.
