I have a good working refinery port, with 10ks of the stuffs we need but I built a ground port first, was grinding the bp for a nice orbital when the planetary issues arrived and so as there is only one orbital slot, dare not build the orbital now!Not all of us use a carrier for it all the time. Though I will admit making more frequent use of one lately due to higher distance to supply stations (I'm the only one who's yet managed to set up a working refinery system in the local region) to make it more bearable.
