In the current version, the body morphs affected the position of the bones is not applied exactly (as is). Every time I apply the same morph to a neutral character, the position of the bones (and the whole character) unpredictably changes along the Z axis in the range of 1 mm (each time the shift is different). This can be detected using "Adjust Bones" or exporting to FBX.
To make sure that this error is present, load a neutral character, apply a morph (for example CC + Neutral Male), check the Hip Bone position in "Adjust Bones", remove the morph, apply the same morph again, the Hip Bone position will be different.
This error causes significant difficulties when creating and debugging new body morphs.
