Picking up wrong materials with multiple benches

[lucidmadness]

I have 4 people working robotics benches. One person making presses thinks he should pick up motors, the guy making skeleton muscles picks up robotics components, and the guy making robotics components picks up presses. I have a mod making cpu assisted repair kits which is also trying to pick up motors (needs cpu and repair kit) and even my limb crafting guy is trying to pick up motors or something he does not need.
