Blitz Grab glitch

Noticed it while playing a game against blitz...at first i thought i was just seeing things but after several more incidents i know this to be a fact. If you stand infront of your minions while they are grouped...blitz grab will grab the minion as it suppose to...BUT! if you stand infront of 1 minion...Blitz grab will go through that minion.....again i repeat if you are standing infront of 1 of your minions and blitz throws his grab at you...it ignores that 1 minion and just goes through it grabbing you. please fix this issue....if you dont believe me fellow summoners i suggest seeing it for yourselves. (keep in mind this glitch works only if there is only 1 minon present infront of you)
