Sliding Nautilus

I believe this is a gameplay bug. When Nautilus uses and misses his Q, Dredge Line, and then leaves sight immediately (and sometimes when he is not visible but you can see his anchor after he throws), such as going into a bush or fog of war, then his animation gets stuck in the "throwing" position with his arm forward. He no longer walks anymore and starts sliding along the ground. I do not have any recordings or screenshots.
