Frost Walker Sprint

When walking across water with Frost Walker II, a bug occurs when you are sprinting and the Frost Walker isn't able to keep up with the sprint of the player but randomly stops. Have done 5 tests, same occurrences. Furthermore, after getting back on the ice, the game updates to where you would have sprinted to and generates the ice there. Furthermore, not sure if bug or actual implementation, the Frost Walker II stops to work at the end of the water stream.
