drones can duplicate quest items

[Veracity0]

I took an existing HTML file in which the last matter duplicating drone duplicated an item and manually munged it so that the monster was The Batsnake, and the item dropped and duplicated was The Stankara Stone.

Before I fixed it, questL11Shen advanced two steps.
Now it advances one step.
