thanks, but I assume that just makes the native american factions not attack anyone or hostile towards everyone else. I'm talking about the natives from both the Americas and India (the latter ones should still be able to function, or india would get rather dull). Also, in my example, the trade offer came from austria (during their turn), I don't know what the "not expandable" feature does, but in my case they just swapped one home region for another, in europe.
