No item in foliage

No item in foliage is an interactable error piece of flora that can be found in the Northern and Southern Forests. Upon being interacted with, it disappears.

The object resembles a blob of Crude Oil. Before Patch 0.3, it used to yield small amounts of it, alongside specific plants that would yield it when cut with the. However, as Patch 0.3 turned Crude Oil to a fluid, and fluids cannot be held in the inventory (unpackaged), the blobs of Crude Oil caused to yield nothing, hence 'no item in foliage'.

As of Patch 0.4.0.0, some rocks in the Dune Desert can be picked up, showing No item in foliage as well.
