Short description of error
Normally, when duplicating an object set, relative reference structure between selected objects to be copied is usually preserved. That is - if a pair of objects, one of them having a variable used by other's driver, modifier etc. is duplicated, a new copy points to a variable in a new paired object (duplication of a character or anything having a rig). That seems not to be the case for the drivers of shape key values. A new object still points to original instead of new respective object.
Exact steps for others to reproduce the error
- Duplicate the selection (empty and a cube)
- Select and move the old empty in Z.
- The effect is on respective object's translation, but on shape keys of both objects.
