Description

Leap motion hands stop tracking after regenerating skeleton. When opening the asset "hands_lo" the user is confronted with a message that reads "The preview mesh hierarchy doesn't match with the skeleton anymore. Would you like to regenerate skeleton?" and after clicking yes, the hands/fingers for that asset no longer track when using the leap motion

Steps to Reproduce
  1. Open a blank project
  2. Make sure Leap Motion is plugged in and set up
  3. Enable the Leap Motion plugin
  4. Restart the editor
  5. Create a new game mode
  6. Name it LeapGameMode
  7. Set the default pawn to "LeapFloatingHandsCharacter"
  8. Set the current game mode to "LeapGameMode"
  9. Play in editor
  10. Move hands and fingers around (The hands/fingers will track correctly)
  11. Stop PIE
  12. Open "hands_lo" (This can be found in Leap Motion Content folder)
  13. Click yes on the error message that comes up (image provided below)
  14. Save
  15. Play in editor

Result: The Hands/fingers no longer track
Expected: The Skeleton would be updated or the message would not appear and the hands would continue to work as expected
