WotLK Bug mision Tirions Gambit

[Sarzak]

Im doing Tirions Gambit quest which basically consists of watching an action but the action has stopped just as Tirion destroys Arthass heart and the cultists surround us.

In that situation I have waited patiently without anything happening

What I can do?

My PJ is Sarzak

I have abandoned the mission and I have taken it again, but when I return there, the scene is as I left it
