[MDL ED] Body Causes Disappearance?

[Mipz]

I'm trying to add a phonebox in to my custom story, but I want the player to be able to 'use' it. I imported the mesh, gave it a body, then saved it, but now it's invisible. It's not invisible in the editor, and it's okay so long as it isn't a body, but turning the shape in to a body seems to be breaking it.
Without a body
With a body

The preview also changes with/without the body as well.

Help! D:

You have to attach the body to the meshes of the model, otherwise the mesh doesn't know where to go and it will default to the map origin point (0, 0, 0). This also goes for lights, billboards, and particles you want on the model.
