Like Ank pointed out, the racial picker defaults to Human if there isn't a 50+ or 30+ for Halfkin races for the "actual" race. The bonuses are all given via the genetics themselves, but the game has to still have an assigned race for general compatibility. It wasn't the most immersive way of handling it, but it got it functional. I have a new calculation I'm bug-testing that will always try to pick the highest, rarest genetics and give that as the "assigned" race.
