When a Botania Rod of the Lands is present in the user's inventory, the Unbreakable Wand sees it as a source of dirt, but obviously cannot place dirt blocks through it, so the white outlines show up but nothing happens. If dirt is present in the user's inventory along with the Rod of the Lands, both are ignored as a source of dirt and no outlines appear. When the Rod of the Lands is not present, but dirt is present, the Wand works as it should.
