To be more precise about my issue, if I switch to SM mode, then go to the system view and create a new NPR race (say Russian Alliance) with as specie Human, then it seems I'm auto switched to this race, and they get a colony on the planet body I selected.
But then, it starts to not work as it worked in VB6. I can't switch back and forth between each race (mine and the various human NPR). When I exit and re-enter the system view, I can in fact only access my race.
I clearly remember in VB6 that I could switch from one race to another and add stuff to each of them, as I wanted. It seems it's either no more possible now ?
