Ziggs Bouncing Bomb interacting with turrets and inhibs

I was playing ARAM and got ziggs. As the game progressed I noticed all of my bouncing bombs (Q) was exploding on initial contact with inhibitors and turrets. This was the case for both destroyed and non-destroyed as well as both enemy and ally. Not sure if this is unique to ARAM or if this is through all game modes/maps... I don't record my play so I can't link a video, but I am curious if this is due to a weird coding change in the latest patch.
