Steps to Repro:
1. prepare a sprite sheet with multiple sprites for rigging
2. in the Skinning Editor, add bones and mesh/weight to one sprite

4. select a different sprtie on the sprite sheet and paste the bone/mesh data

The bones are pasted on to the first sprite and the following Exception is given:

Exception: Selection Exception: bone's skeleton does not match selected skeleton
