Devourer (ghost dog) is visible when you are invisible (BUG)

Call me a noob if you please, but Evelyn is my second favorite champion. And though that is not at all noob-like, I receive much hate for continuing to use the purple jungle rune, now renamed "Devourer." I have my reasons. But what's very unfortunate is that while I am gaining my stacks, though no one can see me in a bush or outside of a bush, they can see an unescorted dog and . . . well . . . let's just say Jinx took a few shots at me while no pink wards were around.

Long story short, or short story shorter, when I go invis so should by 'ghost dog.'
