I have plane spawn rate turned to the max, and warnings on too, but I haven't gotten any planes spawn. Is it a progression thing, and I just haven't gotten far enough for them to appear, or is it a bug? I am currently GSO 3, GeoCorp 3 and Venture 2. I also noticed Many errortechs fall from the sky, and far ones haven't despawned, despite turning on "Remove far NPT bases"
