Just wondering how exactly to modify unit availability ... dismayed that in SS, as in vanilla M2TW, it seems extremely hard to recruit non-mercenary melee cav as the Poles (harder in SS, as you can't get the Knights Templar), I though I'd modify things so I can get the Polish Retainers at the same time I can recruit Polish Nobles. So I modified the export_descr_buildings.txt, but it doesn't seem to change anything. Can anyone please help me?
