Vertex group doesn't follow bone when in game

Attached is a very simple test file.

  • I have an armature
  • I have a mesh, Suzanne, parented to Armature, having one vertex group called Bone.
  • I have one bone (called Bone) with an animation (it rotates)
  • Vertex Groups is enabled in the bone modifier
    When I choose a frame, the mesh follows the bone.
    When I use the game engine, the mesh doesn’t follow the bone. (The UP arrow should run the animation, and the debug display says that the frame number is increasing correctly)

Can’t see what’s up - any ideas? Thanks
