Miss Fortune Q Bug

I am sure this is a bug with her q, at least I hope it is because in the lane phase I just had against a MF she was hitting her q on champions with a minion directly between the minion she used her q on and the champion. It was making no sense why the double up was hitting champions with minions between them and the q. Maybe the game didn't recognize there was a minion or what. Some people told me that her q was randomized but I watched the videos on her abilities and watched a few games with an MF at adc and it was only a couple times that I saw her q go directly to a champion with a minion between the champion and the minions that Mf used q on. That's why I'm reporting it as a bug, and its a pretty dangerous bug that can influence games negatively. Again just reporting what i've seen and not seen after doing 30 minions of double checking
