I overhauling and updating many parts of the code to implement these expeditions and backstories, because it has changed a lot since the old Colonization Modes and the resulting code will be final, out of future expansion.
In this optic, I reworking completely the data structure of the non-player factions and how the data of expeditions and backstories will be managed, and that include the setting up of the populations.
Since the populations in FARC will be multiracial and multiethnic in the future (until now only the humans are present), I decided to implement already the data structure of this future expansion.
So in clear, the population's data structure will support already multiples races and ethnicities but will be only fully managed when I will code and release the alpha 11.
So by this way this avoids to have to redo, one time again, part of the code in these data when the time will come.
That's all for now, thanks for your interest!
