i see they added this to the scripting.lua file...

if conditions.TurnNumber(context) == 1 then
if conditions.FactionName("cherokee", context) and conditions.FactionIsHuman("cherokee", context) then
scripting.game_interface:trigger_custom_mission("britain_protectorate", "cherokee", "capture_city", 0, "Acadia", "", "main_mission_capture_city_text", "main_protectorate_new_spain_reward", 2000, "", context)
end

getting ready for warpath i think.

But this might allow for other things for people to script in if we can figure out how to use all the parts.... like scripting alliances and different such things through missions and such.
