I have a fully charged welder, a fully charged makeshift welder, and an uncharged makeshift welder. I also have all the other requirements (recipe, 7/4 mechanics skill, steel frame (which I also repaired), a hammer, a hacksaw, a wrench, welding goggles, a soldering iron, and 5 copper wires.
The construction screen has all the fields correctly green, except for the ‘1 welder or 2 makeshift welders’ line, which is brown. In my experience, that means that ‘you have this item, but it is currently reserved as being used as a tool for the construction of this item’. But in this case, I am planning on using the welder as the component, and the charged makeshift welder as the tool.
So … how do I get around this? Should items used in construction have batteries loaded in them? And do all components of construction need to be in perfect condition? Is there something obvious that I am missing?
