I helped the Argonian kick the habit, went into the warehouse and killed some people and the only thing I can find in there is some skooma and moonsugar you can steal. And the bodies of the people I killed have vanished, and I don't remember if they had anything on them. Can anyone help me out?

There's a small targetable something on the desk behind the journal or ledger - is that the problem maybe?

There should be a satchel on the table ( in the same room where all the moon sugar and skooma is ). Inside the satchel is a note.

Read the note to start the the next step.

Beware though....... I was doing this very quest last night and the third part on my playthrough is bugged out.

Actually to save me started a new topic. If anyone can explain the third part to me as i think my playthrough is bugged on this quest and i just want to make sure its not actually me and that i should be doing something else.

I go to the cave and eliminate the only 2 bandits in there. I get no other options. Is there something else i should be doing ?

Hhhm, maybe I just picked up the note and forgot to read it. I guess I will have to read all the notes in my inventory, which is a lot. Thanks.

Yes you have to read the note to trigger the next step.

Well hurry up and do it and come back and tell me if the next step went smoothly. Like i mentioned above, i was doing this very quest last night and the next step (at the cave, sorry if this spoils it for you) is not happening for me.

Bugs

• During http://www.uesp.net/wiki/Skyrim:Supply_and_Demand the Jarl in Riften asks you to clear this cave. Clearing it and/or killing some of the inhabitants or the bandit outside the cave may cause it to be unable to be completed.

If this happens, you may need to visit the cavern up to 3 times for this quest to complete. On Xbox, the game seems to look for 7 Cragslane Cavern humans to be killed after the quest is assigned. If you have cleared the cavern before this quest is assigned, only 3 humans will spawn around the cavern -- one outside and two inside. To get the required 7 kills, kill the bandit outside, kill the 2 bandits inside, and then wait in Solitude for at least a month in order to allow the cavern to reset. Travel back to the cavern and get 3 more kills. Finally, wait once more for a month in Solitude to allow the cavern to reset again, and then the quest should clear the next time you kill the bandit outside. If you're playing on PC, you may try skipping this stage by using console commands:SetObjectiveCompleted FreeformRiften01 30 1 and SetStage FreeformRiften01 40 First one to set current stage (disrupt skooma operation) to completed state, second one to set the next stage (report to jarl) to active state. To see all stages of this quest, use the following command: sqo FreeformRiften01

hahahahaha thanks for the help

Hope it helps! Let me know.

I'm having the same problem the wiki describes. I had already cleared the skooma cave before I got the quest in Riften. Hate having to wait for mooks to respawn. I'm up to five. One more month of waiting and then maybe the quest will update.
