a hunter's calling theorick glitch

So I beat Theorick in the Nesaak part of A Hunter's Calling, but then I got stuck in the cutscene and so I did /kill and now the quest is glitched and it says that I need to defeat Theorick even though I already did.

I tried all I could including /kill, /servers, /class, and even using his staff in the temple of time to go back but nothing worked. Could someone please help me please? because It's the last quest and I just want to fully finish the game.

 

Have you tried refighting Theorick? (you have to press a button near the Ice Barrows)

 

I tried it and it worked, Thank you!
