Hello, I wanted to script quest We’re Here to Do One Thing, Maybe Two…, this quest start with spell 77847 (Summon Krom’gar Wagon), then 77848(Aboard the Krom’gar Wagon). spell 77847 correctly summons Krom’gar Wagon, it is vehicle with two accesorries - kodo and wagon. I summon them with table vehicle_template_accessory
INSERT INTO vehicle_template_accessory (entry, accessory_entry,seat_id, minion, description, summontype, summontimer) VALUES
(41736, 41742,0, 1, ‘We’re here to do one thing, maybe two’, 8, 0),
(41736, 41737,1, 1, ‘We’re here to do one thing, maybe two’, 8, 0);
It works, however, on the wagon, some more NPC should sit:
INSERT INTO vehicle_template_accessory (entry, accessory_entry,seat_id, minion, description, summontype, summontimer) VALUES
(41737, 41738,1, 1, ‘We’re here to do one thing, maybe two’, 8, 0),
(41737, 41739,2, 1, ‘We’re here to do one thing, maybe two’, 8, 0),
(41737, 41740,3, 1, ‘We’re here to do one thing, maybe two’, 8, 0),
(41737, 41741,4, 1, ‘We’re here to do one thing, maybe two’, 8, 0),
(41737, 41741,5, 1, ‘We’re here to do one thing, maybe two’, 8, 0);
.
When I summon wagon (41737) separately (.npc add 41737), those npc are summoned. However, when I summon 41736, 41737 doesn’t have its accessories 
Both on 4.3.4 and 6.1.2 branch. Is it my fault or TC bug?
(of course I have also npc_spellclick_spells:
DELETE FROM npc_spellclick_spells where npc_entry IN (41736, 41737);
INSERT INTO `npc_spellclick_spells` (`npc_entry`, `spell_id`, `cast_flags`) VALUES
(41736, 46598 , 1),
(41737, 46598 , 1);
