Niko, I looked at your file...
Basically, your duplicate function is fetching the constructor of what you're sending it, which is cast as a MovieClip... so it's calling the constructor of MovieClip, which is obviously just an empty movie clip. To fix this, I just set the Linkage Properties of the two symbols to arbitrary names, (which I would do whenever I hoped to declare them as classes). So, the only question is, why did it work for the top level symbol and not for the bottom? I believe this is because the top level symbol contained another named MovieClip inside it, in essence giving it a property and forcing Flash to store it internally as a class, to which it arbitrarily assigned the name of "Delete2_1", regardless of it being assigned a Linkage identifier/classname. So, make sure any symbol you want to duplicate has a classname defined in the library. -jonathan P.S. Read up on that "automatically declare stage instances" checkbox and why it sucks!
