Deep Copy does not maintain document reference order.
When deep copying documents with child document references, the order of the child document references is not always maintained.
Have a Document A with an attribute category that is referencing other (child) documents (at least 3 documents in one document reference attribute) in a "library" project.
Deep copy the Document A to another Project B using a project/document attribute category with an accordingly configured Saved search document source.
Expand the attribute category of the deep copied Document A in Project B and check the order of the document rows representing the child documents of Document A.
You will see that (often) the order is not maintained.
