Bottom turret did not fire for one side in a 3v3 game

I just played a 3v3 game on twisted treeline and our bottom turret did not fire. Minions and champions were both in range, sometimes for long periods of time, say 30-60 seconds hitting the turret and it did not fire a single shot.

I'm not sure what else to provide, is there a game ID or something? The only oddity was there were 2 garens with dread knight skin. Otherwise, I have never seen this happen before.
