There is also a very IMPORTANT thing with this table, lords like Karl Franz and Volkmar which share faction and starting position also share this table (usually it is named by the first avalaible Lord: KF, Mannfred, Thorgrim, Archaon) and they have to share one unit at least. It also “spawns” the starting armies, so if there is some missing lord here their armies will not spawn.
“start_pos_land_units” contains every unit (but the ones we set in the other one) of each starting lord of every faction, playable or not. I usually put here the most powerful units of each legendary lord but there are some exceptions. “start_pos_starting_general_option_additional_units” contains the additional units that are showed in the faction selection screen for each legendary lord (for example Tyrion’s silver helms, white lions and chariots).
