Umbala level 4A weapons

[Mattex]

I cant seem to start the sabbath quest.

Ive done the umbala language quest. i've gotten all the items needed.
i have them ON me - not in the cart

the NPC in question is in map "um_in 156_77" He says something on the lines of "you have no business with this old man, go continue exploring"

He doesn't ask me for any items nor does he respond to me holding all the items.

Someone told me it might be cuz i started a diff quest in umbala or niffle. which i dont think i have as i havent talked to any other npc's.

if anyone can point out if i've done anything wrong or missed something, it would be greatly appreciated.
