Why is "TorsionSpringConstraint" invisible even when set to visible?

I turn on the visible property, and when I run the game, I still can’t see it. Please help

Thanks!

Anyone?

Most of the constraints’ visible property don’t actually work, save for Rope and Spring


^ both constraints (Rope and TorsionSpring) are visible, but only the Rope is actually visible in game

Alright… that seems like a bug… How can I recreate the torsion spring then so that I can see it in game?
