I was going to do the quest line to unlock Lokkar, and when I went to the house to loot Nane’s stash note, it did not drop from anything in the house. I looted the chests and body. Yes I am on ultimate difficulty. Am I missing something?
Welcome to the forum. 
Did you go to the right house?
And the correct chest? If memory serves that house can have two chests in it.
I missed the significance of the note. The actual stash is located elsewhere.
