Necromancer Skullcap question

[Rasah]

I had my quest components eaten today, and I'm wondering if I did something wrong.

I did skullcap #1 - Turn in 4 sarnak brains, get skullcap #1
On quest #2, I got a torn and a ripped tapestry. I combined then successfully. I then turned it 2 items. Skullcap #1, and the combined tapestry. I got nothing in return.

Did I screw up somehow? Was I supposed to get 2 of each torn & ripped, then combine them together, then turn in 2 faded tapestries along with the skullcap #1? I know it's only 1 step, but I hate that I wasted all that time to lose it.
