That's pretty weird. Is this a randomly generated system or a loaded one? It has worked ok for me so far.
Randomly generated - the new lobby seems to generate planets randomly every time that you change the number of player slots. I don't know whether some other mods are conflicting with it.
I 'fixed' it by removing the mod from new_game entirely, whatever it was meant to do there before it wasn't afaik. You can always add it back later. And added a new theme, 'random'. It's only random within a biome though (metal planets are named after alloys, earth planets after different names for earth, moons after moons in our solar system etc). v1.2 on PAMM. edit: I haven't taken over maintenance of this mod.
If you do the work in making a list of names for each planet type, I will definitely add it. Make a post like this one and then all I have to do is put it into the mod.
FWIW, if it hasn't already be suggested... I vote Dune: Arrakis Chapterhouse Corrin Giedi Prime Ix Junction Kaitain Synchrony Tleilax Richese Old Terra Salusa Secundus For ones other than my favs http://dune.wikia.com/wiki/List_of_planets
Sadly I let this mod die many months ago. I started too many mods and had to let some go in order to stay sane. It kind of worked. I'm mostly sane.
Pity. Seems like a relatively simple way to make the universe feel more alive. I was going to suggest lexx planets also. I'd like to see more rpg elements applied to the galactic war mode.
