When I rename a graphic I am reusing throughout my file, all links to that graphic are lost and when I try to copy layers containing those linked graphics, Illustrator reports the following errors:
- "the document contains pdf objects that have been reinterpreted"
- "an unknown imaging construct"
- "an unknown shading type"

If I have many instances of that artwork in multiple layers, it takes a lot of time to have to find every single instance, delete it, drag the renamed graphic in, move it to the correct layer, resize and rotate, and reapply the styles I had before. This makes it very painful to use the program.

If the program could simply keep track of the fact that I renamed the graphic and update its links, that would save me a lot of time and would prevent doubling my work for each instance of that artwork.
