[GAMEPLAY] Lucians double shot missfiring

First 2 times it happened i chalked it off as internet lag spike but the next 2 times i was like, ok... wth. It didn't happen every time, but i'd be solo farming a lane and dash into the lane with E and the double shot wouldn't go off. One time it happened when I cast Q as well so i dont think its limited to one spell. I was attacking immediately after casting a spell too (Q, W or E). I also had a static shiv and a sheen so maybe the on hit affects where causing an issue
