Skin doesn't move properly
 

Hi!

I've modelled some kind of robot. To move the arms and legs, I've created 4 skeletons and did Skin>Bind Skin>Smooth Bind for each arm and leg.
I've grouped the whole robot including skeletons and so on to one group. When I select the group and move it around all parts of the robot move with it. The skeletons also move with it, but the bounded skin (2 arms and 2 legs) move slowlier than all other things and I don't know why. This means they are not on the final position where they should be, because they dont move proportional with all other objects.

Anyone else had this problem?

I hope someone can help me.

thx,
