Quest Issue: Problem with 6th Necro Skullcap Quest

[Zakaton]

Keeper Rott in West Cabilis gives out the 6th Necro Skullcap quest. He initially cons indifferent and refuses to give the quest and responds to "I am the chosen occultist" with

'When you have shown more devotion to the Brood of Kotiz, we can discuss such things.'

This is normal and expected if you haven't done the faction work. So, I spent 5 and a half levels in WW killing Bandits and maxed out both my Brood of Kotiz and Legion of Cabilis factions. He should now give me the quest, but he still cons indifferent and refuses.

Edit: And yes, just for the record I've completed quest 1 through 5 and have my 5th Rank Occultist Skullcap. I'm not trying to skip ahead or anything like that.

Also, I guess this should have gone into the Kunark section under Quest Issues. Sorry about that.

Further Edit: I was told in game that Keeper Rott doesn't actually give you the quest, he just tells you that you need to gather the parts and return them to Master Kyvix. And that you don't actually need to do any faction work to do the turn in. Setting aside the amount of hours I might have wasted doing faction work, does anyone know if this is true? My recollection from doing the quest on live is that you can't complete the quest without the faction.

I turned in 34 stacks of bone chips and found that raised my faction with the merchants, including Keeper Rott, up to amiable. He still won't give me the quest text though.
