It happened regardless of what order I scored high in. In that screenshot, I had scored highest in celestial, then got points in lunar, and then death. I tried again after getting lunar first, then celestial, then nature, and then I just got 4 points in death and it swapped to death. Another time I did celestial, 4 points in death, and then nature, and it stayed as death again, even though everything else was higher.
Oof, that's good to know. I'm definitely going to have to play around and see where I messed up. Thanks so much for testing out the game mechanics and letting me know about the error. Divine Dominions will play a major role in determining the trajectory of certain scenes in the story moving forward, so I need to get this taken care of before I release chapter two (which is over halfway written).
