When toggling crouch whilst fishing, the fishing rods line snaps rapidly off the rod and then snaps back on to the rod again. This is a visual bug in any view and happens every time the player crouches.
The fishing rod line also has a gap between it and the rod whilst fishing causing it to not be on the rod model in the players hand.
