Hello :) Sorry for the long post incoming...

I have a lot of custom empires, and since the game tends to not spawn custom empires much in my experience, I have them all on forced spawn so I actually get to see them. I'm not sure whether this mod is intended to be used like this though, because even with having made compatible custom empires, they don't show up together.
For example, if I pick a Lost Colony empire, then the associated homeworld I made won't necessarily spawn, and is usually replaced with a randomly generated empire. The same happens with an Interstellar Exiles/Contested Capital combination, picking one won't make the other spawn and I'll instead get a random empire.
If I only force those empires to spawn, then it seems to work as intended.
This happens without any other mods enabled.
I'm not sure if it's supposed to work with all custom empires force spawned, I was just curious whether I was doing something wrong.

Is it possible to have multiple Interstellar Exiles for one Contested Capital? I made 3 empires, one of which is the invader, the other 2 being different refugees of the same species. With only these 3 force spawned, if I pick refugees 1 then the invaders also spawn, as well as refugees 2, but there'll also be a fourth empire with the same species as the refugees as a Contested Capital. Both refugees have the same distant origin 3 trait, and the invaders have the homeworld 3 trait.

Also, if a custom Lost Colony AI empire that I didn't pick spawns, then there just isn't any associated empire that spawns at all.

If the mod isn't meant to work with all custom empires, is that something that'd be possible to mod?
