I'm not sure if this is directly from this mod or not, but I'm sharing it because this mod is the one listed.

I had this same problem. Had to unsubscribe:steamsad:

Oh, I had very similar error, but only after adding Roo's Fawn and Satyr xenotypes.

Tested it couple of times, went that way:
* only Genetic Drift -- world generation fine, pawns spawning fine, all fine
* only Roo's Satyr and Fawn -- all fine, Satyr pawns spawning correctly
* Genetic Drift + Satyr/Fawn -- one time factions didn't generate at all, also debug spawning Satyrs or Fawns didn't work

In my case the mod worked perfecly fine but after tweaking mod options for the next playthrough the faction generation completly broke

I get the faction generation error when combining this mod with certain mods that add xenotypes. Det’s Stoneborn being one example.
