Limits of the Prismatic Constraint

I’m making a part that can rescale and would apply physics to the objects around it (eg. transporting objects on top and pushing objects out of the way as it gets bigger) while doing so. I’ve come up with a prototype that involves changing the Size property of the part while allowing a prismatic constraint with its ActuatorType property set to Servo to move the part. The end and desired result is this:

However, that is how it appears only on server-side. On client-side, the position doesn’t appear to be applied. The physics also does not work on my player character.

Reading through the sliding ball constraint documentation, I did see that setting ActuatorType only allows it to “attempt to” move objects. So what about setting the part’s Size property prevents the prismatic constraint from moving the part on client-side? Are there ways to get around it?
