Animation Problem


I made this model of a sword that transforms into a lightsaber-like weapon. However, I noticed that if I tried to make the sword move while transforming, the energy blade and some other parts would not move in sync with the rest of the object. Oddly enough, the physical blade pieces move just fine. Please let me know if there is a way to fix this!

Attached is the .blend file, run it in blender game and press space to activate/deactivate the sword.

Thanks in advance.
