Hey guys, sorry your update is not working. You are running in a dead lock. oiling can not be reached any more. To build an PumpJack or an Rafenery you need to build this in the Rebotic Assembly Line. To bild this one you need to have an electric Motor. This one can only be build with Circuits. And to build Circuits you need to have an Epoxy and Plastic which can only be build with an Rafenery. So, dead lock. You need to redesign here the tech tree.. ;-(
