Unity3d version: 5.3.6f1
OS: OSX

When I open the HighPolySkinnedMeshDrivenByLowPolySoftBody scene, there is no error. But when I run the scene in editor mode, I got such errors:

Thanks for reporting the problem.

Fixed the problem. It was caused by a bad meta file which caused the BSphereShape not to 'stick' when added to GameObjects.
