In the Sorcerer's Sanctum in Stormriven, I defeated the boss but Karolak Nightspinner did not show up so I could talk to him. I exited the Sanctum and re-entered. I defeated the boss again. Karolak Nightspinner still did not show up. I repeated going in and out about seven times. Still Karolak Nightspinner did not show up so I could talk to him. Please help me.
