FBX issue, reset bind pose messes up Joints.
I have tried it in other software too. The same thing happens. I have done this before with no problem. 
Anyone else?
I import a Fbx CC3 Character, then I pose the Character and when I reset the Bind pose, the joints are messed up..

Issues Resolved. in the Weights tag, some joints left out in the FBX file. once I added then in, reset works fine.
