ARAM Structures Bugs (Towers and Inhib)

You know how Nexus Turrets health bar disappear after the inhibitor respawns? Well I was playing ARAM and stumbled upon a bug where Super Minions and Wave Minions continue to attack our Nexus Turrets even thought he Inhibitor respawned. The Health bars never disappeared.

Small bug I found that could cause some people to go "What?"

Couldn't take a screenshot since I noticed the last second.
