The secret quest tied to the objects behind the trader in Ravensthorpe appears to have no reward attached even though the quest giver mentions 'compensation' upon completing the deliveries. I cannot tell if this is a bug in the quest structure or that the giver say there's a reward even though there isn't and they never updated the mission dialogue to match.
If it is a bug, it is possible that I tripped up the sequencing because I delivered the objects before talking to the Ravensthorpe trader at all. So upon completing the deliveries I was trying to figure out how to trigger a mission complete state and went to talk to the trader. She then had a piece of dialogue which was obviously supposed to be the START of the mission not the end. When that dialogue finished, I talked to her again immediately and then got the mission END dialogue (the bit where she mentions 'compensation'). After this was complete that was that, nothing, no reward or whatever was intended (or not) to be there.
