Snapshots

I recently tried to use the Snapshot functionality in Xcode 3.0 to save my files as they were at the time before I made a change to the code. This change involved creating a new file (may or may not be important). After I made the change and found that it didn't work the way that I hoped I tried to restore to the snapshot that I had taken. In stead of restoring my files to their former glory, it DELETED all of them.

Has anyone else had this problem?
