Pet bugs, voidlings, plants, etc....

This past week I've noticed while playing Malzahar that his voidlings bug out sometimes. They won't attack targets, turrets, minions, etc. I thought this was a one time thing but it's happening every game now. I also thought it was just Malzahars voidlings but I just got done playing Zyra and her plants did the same thing. They'll attack a target but then once that target dies (minion or champion) they just sit there and don't attack. With Malz I know it's not just me. I had a Malzahar mid on my team yesterday (it wasn't me) I was jungle or something, doesn't matter. Point is I saw his voidlings do the same thing, attack for a bit and then just stop. Not sure who or what else this effects but Malz and Zyra for sure have bugs.
