When I try to build a screw pump with
bMs, I see the red text:
Needs screw trap component
I've already built seven pumps, and still have blocks, pipe sections, mechanisms and enormous corkscrews to go. Nothing is forbidden, and no burrows are activated. What could I be missing?
Edit: It does work now, and AFAIK nothing changed. So the question is: What could I have been missing?
