Korvik the Cursed

[tinktankzero]

My friend and I have been searching for old Korvik for the past four nights. We've been doing circles around the zone, patrolling the spawn points revealed on the talk page of the p99 wiki. We've cleared every willowisp we've seen, and killed Ashenpaw, Grimfeather, and Grimtooth several times, but Korvik has never spawned.

I expected it might take a while, but having four nights of no-shows seems excessive. Am I missing something? Has his spawn been disabled, or am I just lacking the persistence and dedication necessary for him to appear?
