Current Outstanding bug(s):
-Using Q while autoing a unit where your on attack effects do not apply. I.E. Jax E and Teemo Q (Blinded) will fail to grant the next stack of Q and remove the buff entirely (if on first stack) or fail to progress the stacks but still reduce your cooldowns until the buff expires (on 2nd or 3rd stack).

-Guinsoos will apply the 2nd stack of Q and cause your 2nd Auto after casting Q to knock up. Dusk and Dawn does not have this interaction. This should not be the intended interaction as this was not true prior to the Q fix from this patch.
