Ahri Charm and Orb [GAMEPLAY]

A few times on the map in the last week i have noticed that when i use my orb, it hits an enemy but does no damage like it normally does. Other times i hit an enemy in the same way with the orb and it does do damage.The way i play is i throw the orb so that it hits them at the tail end dealing both attack and magic damage at the same time right before coming back. and recently its only been working some of the time. i see it hitting them but only sometimes does it do damage. my charms have been just not doing anything when it hits them on the tail end too. i see in gameplay the charm touching them but no attraction happens. I have a really bad one that happened yesterday. i sent Charm at a Kayle and it passed right through her and kept going. she didn't ult, no Banshees Veil... nothing to explain this. it just sailed on through.I have noticed similar bugs with Blitz Arm Grab, and Amumu's Grab. Please try to fix this soon :) and keep up the epic work. ttyl
