Description

Un-checking the ContributeToMass setting on any part of a physics asset results in an ensure when simulating physics. 

Steps to Reproduce
  1. Create a 3rd person template project
  2. Open up the physics asset for the mannequin
  3. Select one of the shapes and change the ContributeToMass to false
  4. Simulate physics 

Result: The Editor locks up for a moment and then throws an ensure to the output log. The mannequin also disappears as a result until you stop simulating physics.

Expected: The physics asset would simulate normally with the selected shapes not contributing to the mass of the asset.
