Mesh Disapears while using Softbody physics

So I have been working on a character in Cycles using Softbody physics and everytime I press ALT+A to check it out the mesh disappears and only the Bones stay playing the animation.

Why? I used Softbody physics in the past in older versions of Blender and I never had this. Is there something new in the latest version I need to toggle? Why does my mesh keep disappearing?

Whenever I open this thread the blend file you must have attached to your post to aid anyone wanting to help you has also disappeared.

Son’t bother. I give up on Softbody. It’s completly Random!
