Minion Glitch

So during a few matches with my significant other, we both noticed how the occasional minion horde would suddenly be running in place, with nothing obstructing their path. Some would ever just stand there whilst turrets or enemy champs mowed through them, without once fighting back. And then tonight, we both had similar effects on our own characters. We'd be fine and then suddenly her character is teleporting into a bush and mine is walking though a turret. It's not really ruining game play for us but it might lead to more dire ramifications.
