Added a loot quest for "Horse Dung" (items get taken from iventory when being picked up). The items don't get swallowed by the quest and there is no progress. 

Horse dung is no pickable i think. Its like an item that lay around. When you make an loot quest for jackets for example they have to take from a loot box. Dont work when they take from the ground.

I just saw that this was posted a while back also. You're right, it's difference between the "picking" from the ground and the "Looting" from a container. It's why the "Loot" option quests for grubs and worms aren't working either. Anyway to just add a new category for "Picking" that allows us to do these type of querky quests?
