QUEST BUG: Stonefire Machinations bug

Azurephoenix999

When I went to disrupt the dark anchor ritual, I defeated the three bosses only to have the Pinon (or whatever it's called) not spawn. Then, after a few seconds, the bosses respawned and I had to defeat them again. Afterwards, the exact same thing happened and I had to beat the bosses a third time. Then the Pinon finally spawned and I could continue with the quest.

Please fix this so it isn't as much of a pain in the ass to players in the future.
