Thanks! I did note one thing on the weebly which is not correct based on my testing...
After much trial and error I found which races will be listed 1st are in the order they are in the entity.manifest. The original order was...
What I found was this is driven by selectable priority with the higher value listed first in race selection.
I made my Nephilim race 4 and Plague race 3 and TECH which is already 2. Then I used your technique and put Psi as the race below Nephilim and Vasari as the race below Plague.
Not sure yet if the SoA team wants to keep it but I put the Pirates and NPCs in the 6th slot.
I plan on adding a third race as a human based faction so I left out the NPC for now.
