Чтобы иметь возможность не только давать вассалам солдат, но и забирать у них, надо в module_dialogs поменять строчки
(change_screen_give_members, "$g_talk_troop_party"),
на
(change_screen_exchange_members,0),
там их должно быть 2. (для лордов и патруля)
P.S. - Если написать (change_screen_exchange_members,1), то и самого вассала сможешь забрать в свой отряд. Хотя это наверно уже перебор.
