Two types of geometry are copied when you create a Copy Geometry feature: explicitly copied geometry and implicitly copied geometry. Some geometry references that you select (such as explicitly copy), include implicitly copied geometry. For example, if you select a surface for your Copy Geometry feature, the surface itself is explicitly copied and the edges of the surface are implicitly copied.

If you reference any implicitly copied geometry of a Copy Geometry feature, and then reroute the copy Geometry feature references to new source geometry, the implicit reference fails because the original parent geometry (the implicitly copied references) are no longer available. Therefore, make sure that you explicitly copy (select) all pertinent geometry in a Copy Geometry feature. Otherwise, you may need to redefine features that reference implicitly copied geometry.
