Holy crap, that looks overly complicated.
I am taking the planets from Maelstrom mod. I exactly don't know how they implemented the moons 'cause I am kinda novice at modding. I could try bunch of things zombie said, but just in case all fails (due to my novice skill), another route would be implementing new planets without their moons.
Is there a way to strip the planets out of their moons so that I don't have to deal with this complicated mess? (well, unless removing the moons from planets gravity well is harder, i will be sticking with implementing planets with moons).
