I've turned off both the "No Dropped Sand (Sandgun)" option and "No Dropped Sand", and when I place sand that will drop, it both drops the sand and produces an item. This results in an infinite sand duplication. I'm attempting to level a desert by dropping sand from high up. Additionally when destroying sand with a pickaxe, I receive sand items equal to the one I destroyed plus all blocks that moved down one, while the blocks that moved are still there.

I'm going to assume these duplication glitches are not intended behavior, so it might be worth looking into. I would like to hard disable the new mechanic this adds to produce items from falling sand.
