[GAMEPLAY] Garen -Ryze Running Away From Turrets Near Nexus Makes longer Kill Range Than Ussual

Running under two turrets under Nexus with Ryze and after killing a champ, turrets focus Ryze and when he runs away turrets keep focusing him far more than usual and he takes damage normally as if he was still under turrets.

I've played few games with Ryze, and it happened in 2 of them. Same thing happened every time near end game.
