In Space Engine, the procedural generation of moon orbits appear unrealistic and would be unstable in reality. Procedural planets with many dwarf moons (about over 70) may sometimes group them into an inner moon system and an irregular moon system, just as usual. Viewing the orbits of the irregular moons, some have orbital inclinations of 60° to 130° to the planet's equator. I've checked the orbital inclinations of irregular moons in the solar system (Wikipedia list of gas giant moons) and it appears that none have orbital inclinations between 60° to 130°.
Regarding procedural large inner moon systems, I'm not sure if that's also realistic but it would be a nice touch if they form a ring of debris.
I'm not sure if the irregular moon orbits were already fixed in 0.990, but I've decided to ask since I can't find any mention of this here.
