Hi,

I've got to the make electromagnetic actuators part of Liberty Reprimed, and even though I have way more than enough materials at the airport workbench;

Circuitry 370/5

Screw 314/1

Steel 981/10

Fiber Optics 120/3

Rubber 316/5

High-Powered Magnets 4/1

.... the "(A) BUILD" option is dimmed & I can't make the damned things.

Any ideas please?
