I'm having problems xrefing in a drawing that contains a data shortcut in Civil 3d 2014. Whenever I xref this drawing, it converts some of the civil 3d objects into the proxy state boxes, and gives me the error that the drawing was created with a newer version of civil 3d.
So far it appears to be only one drawing doing this. The drawing I'm xrefing in contains alignments, & profiles.
Does anyone have any ideas as to why this might be happing?
Thanks
