[Gameplay] Azir Turret Not Visible to Ally

I was playing an Azir game earlier today with my team being Rumble, Vi, Azir (me), Tristana, Alistar and the enemy team was Nasus, Amumu, Akali, Twitch, Karma. At one point during the game our alistar (who i was in Teamspeak with) disconnect from the game. While he was disconnected I summoned an Azir Turret on the Outer Mid turret rubble of Purple Side. (He may have actually been connected when I summoned the turret Im not sure.) When he reconnected to the game and rejoined our team in mid he asked me "Why do we have vision of their ward?" because he could not see my Azir Turret, upon him saying that he couldnt see the turret (which he knew where to look because there was an in sight ward defining which turret it should have been) I immediately checked to make sure my turret was still up. My Turret was still up (about to time out but still up) and he still couldnt see the turret.

This seems pretty game breaking to me not being able to see an allied turret.

TL;DR Disconnecting from a game while Azir Turret is summoned appears to result in Azir Turret not visually appearing for the disconnected champion when he reconnects.
