I have issues with a few of the craft files linked in https://kerbalx.com/ Crafts like "Apollo LEM" (https://kerbalx.com/minepagan/Apollo-LEM) and "Vega" (https://kerbalx.com/minepagan/Vega) say there are missing parts (bluedog.Saturn.S4B.SLA.Full, bluedog.Vega.Avionics, bluedog.Vega.Tankage, bluedog.Vega.EngineMount and bluedog.Vega.Engine, etc.). Where do i find these parts?
