Illaoi e bug with Ashe volley

Ashe's volley blocks illoai's e as of the arrows were minions. Happened several times in my last game against Ashe. Was very frustrating trying to land e's when she can block it by shooting at me. Recreating should be easy, Ashe on one team illoai on the other, illoai tries to e and Ashe uses volley at the same time.
