I imported a figure based on DAZ's DAZ4Kids. The Exported an FBX from DAZ and imported it in 3dXChange and then brought it into iClone.
Please ignore that the hands are so close to the body...I didn't adjust the arms into a proper T-Pose so they are somewhat offset.
However, when I move the resulting character (via animation or just translation), I get parts of the character seemingly sticking to a fixed point in space.

 

Could this be because of the improper T-Pose or is something else responsible for the crazy-glue behavior?

What i wrote for 'Scrappy" should work for your character too...
