How to Merge Scene with Asset Server

When using the Asset Server to merge two *.unity files all objects in the Scene Hierarchy are deleted. The scene is completely empty.

I have attempted this on multiple machines with the same results.

There are no errors reported.

Reloading the scene does not restore the objects.

Is it possible to merge scene files using the Team Asset Server?

Has anyone else run into the problem I described?

Thanks!

Update

I found that I could actually look at the ascii version of the binary data. Here is what the entire *.unity file looks like after the merger:

 ------Import Settings------
 
 fileFormatVersion: 2 guid:

 DefaultImporter:   userData:

And here is what the start and end of the file looked like prior to the merger (I cut out most of the class information since it is so large):
