Return of Reckoning

Hello,

I can't finish two quests in the dwarf capital:
https://ibb.co/rptNHcz

The first one is "Defendin the deeps":
https://ibb.co/rQhVgzF
-I can't find the "black powder keg".
- "Crate of tallow candles"
- "Box of pressure gauges"

The second is "Snail mail":
https://ibb.co/GCQq6cr
-I can't find the "pest" to kill.

Do you know of any problem with these two quests?
What should I do to unblock the situation?
Thanks in advance

I understood the problem thanks anyway

The pest is a spider in the kitchen storeroom on the ground floor of the citadel.

I don't remember where the black powder keg awas, but I did finish that quest so it's definitely somewhere.

Under general discussion I posted a city quest guide for karaz-a-karak https://www.returnofreckoning.com/forum ... st#p500100

It's ok thanks all
