I'm new to the Kethane mod, and having a similar issue. I have Kethane 0.4.3 and latest version of kerbal. My mining rig has tanks, drills and a detector, but i'm still not getting any kethane, is the converter neccissary to be on the rig to extract the resource? My plan was to mine with my mobile rigs, transfer the kethane to a processing plant and convert it there... Please help
