Scripts

Hello, could you please help me? I'm having a problem with this part of the script.

function fb1()
RemoveHeroCreatures("RedHeavenHero03", 8, 20);
sleep(1);
RemoveHeroCreatures("Biara", 20, 1*D);
sleep(1);
StartDialogScene("/Maps/SingleMissions/Warprolog/StartScene2/DialogScene.xdb#xpointer(/DialogScene)");
sleep(1);
MoveHeroRealTime("Biara", 88, 59, GROUND);
sleep(1);
Trigger(REGION_ENTER_AND_STOP_TRIGGER, "stfb1", "fb1", nil);
end;

Trigger(REGION_ENTER_AND_STOP_TRIGGER, "stfb1", "fb1");

The problem is that after Biara makes her move, this cutscene, StartScene2, plays a second time, specifically within this trigger. There are no other mentions of it. If anyone understands, please tell me what might be the cause. I've been racking my brain over this.
