Oh, my. And who is that in the lower left corner? Wier?) What does the console say? I'll take a look. Everything worked for me. Has the task of defeating Marbas been completed?

function finishF()
if IsObjectInRegion('Alaric' , 'finish') == true then
sleep(7) -- sleep or wait for player 1
BlockGame()
sleep(7)
Trigger(REGION_ENTER_WITHOUT_STOP_TRIGGER, 'finish', nil) -- final3
sleep(1)
StartDialogScene('/Maps/SingleMissions/NewRandomMap 43/StartScene7/DialogScene.xdb#xpointer(/DialogScene)');
sleep(7)
SetObjectiveState('obj5' , OBJECTIVE_COMPLETED)
SetObjectiveState('obj0' , OBJECTIVE_COMPLETED)
SetObjectiveState('obj1' , OBJECTIVE_COMPLETED)
sleep(10)
LevelUpHero('Nymus')
print('win!!!')
sleep(10)
UnblockGame()
Win()
end
end

Try entering @startThread(finishF) in the console.
