Trying to play the animation with a rigid body cube parented and weight painted with an armature bone causes a crash in blender 2.8 Beta (2019-02-06)
To reproduce the error, follow these steps
- Add an armature
- Auto weight paint it (ctrl p) to the default cube
- Select the default cube and add rigid body in physics tab
- Play animation
The attached example will not crash directly when playing the animation without rigid body option first deselected and selected again!
