Bad Scale

Hello,
I have a little problem, when I import my skeletal mesh from blender, one of the objects has a wierd scale, and when I change this scale then I hit save, the changes are not saved :confused:

You should probably fix that in Blender, select the object/bone and do Apply Object Transforms and select scale.
