[CLIENT] Heimerdigger turrents continue shooting (no damage) after Zilean ult

After being attacked by Heimerdigger's turrents I used Zilean's ult to revive myself on death. I then noticed that Heimer's turrent was still attacking me even though I was well out of range. Not 100% sure if there are any other variables but I did capture it. Link to the video is in the post.
