The "Save As" and "Open" buttons still used an old implementation that assumed you were talking about files only in the "./maps" folder instead of loading them from the user's levels and doodads folders. Now all of the menu buttons in Edit Mode intelligently open files the same as the `edit <filename>` command from the dev console. You can omit the file extension and it will attempt to load a Level before a Doodad to find the first named file, or provide the full extension to be specific.
