{Gameplay} Corki Rockets go Through Tagets

I just got done with a ARAM and my rockets were going through/not hitting champions within the hit box, i don't know if knock ups count, but there were points where Alistar would knock up an opponent and the rocket would go right through the target. I don't play corki very often, but it just seemed weird tome, I even asked my friend if I was seeing things, but he saw them go through too.
