Under the linked section of the guide site, it’s stated that the Stop event on movers can be used to stop their movement on a dime. While the mentioned mover’s Stop event doesn’t currently work, it’s also just not the right event for this use case.
The Stop event resets a mover to it’s original position and ceases any control over connected objects. In this case, Pause should be used, as it accomplishes the stated goal.
