Are Bodymovers broken? [Not respecting the massless property]

I’m currently having a problem with bodymovers, I’m not sure if it’s something that im doing wrong, however, massless parts still require the Mass in F = ma for them to move.

Both parts are massless, one is anchored and you can see the amount of force required to move the part upward,

It doesn’t work if i apply a force of “1” and when i go ahead to print the mass of the part, it returns a number, meaning that the part is not actually massless even though in properties “massless” is checked off.

Am i missing anything?

The Massless property only works when it is welded to another part that has mass. If the part isn’t in an assembly or is the root of its assembly, it will still have mass. This is expected behavior.

Ohhh that makes sense now, I was so confused about it, Thank you so much
