求助PY语法跟随商队的问题

gamemi

暂时没出问题的代码块，所以我就折叠了，虽说有些依然看不懂。

(set_spawn_radius, 1),        (spawn_around_party,"$g_encountered_party","pt_officials_caravan"),##呼叫跟随者     (assign, ":quest_target_party", reg0),     (party_set_ai_behavior, ":quest_target_party", ai_bhvr_track_party),     (party_set_ai_object, ":quest_target_party", "p_main_party"),     (party_set_flags, ":quest_target_party", pf_default_behavior, 0),     (quest_set_slot, "qst_escort_officials_caravan", slot_quest_target_party, "pt_officials_caravan"),     (quest_set_slot, "qst_escort_officials_caravan", slot_quest_current_state, 1),     (str_store_party_name_link, s8, "p_town_4"),       (setup_quest_text, "qst_escort_officials_caravan"),           (str_store_string, s2, "@Escort the merchant caravan to the town of {s8}."),          (call_script, "script_start_quest", "qst_escort_officials_caravan", "$g_talk_troop"),

(store_distance_to_party_from_party,":caravan_distance_to_destination","p_town_4","$caravan_escort_party_id"),                                                                   (lt, ":caravan_distance_to_destination", 2),                                                                   (party_stack_get_troop_id, ":caravan_leader", "$caravan_escort_party_id", 0),                                                                   (party_stack_get_troop_dna, ":caravan_leader_dna", "$caravan_escort_party_id", 0),                                                                     (start_map_conversation, ":caravan_leader", ":caravan_leader_dna"),

出问题的在下边，所以不折叠了。
(call_script, "script_end_quest","qst_escort_officials_caravan"),
(quest_set_slot, "qst_escort_officials_caravan", slot_quest_current_state, 2),
(assign, "$g_leave_encounter", 1),
(call_script, "script_change_troop_renown", "trp_player", 20),

这串代码运行完后，任务结束，不过跟随的officials_caravan还是没有消失掉，而且一直跟着~~~~~~~~~~~~~~~~~~
所以要如何让他消失掉？
