Current questions and answers regarding the map editor.

After restarting the computer, nothing can be restored, so it's too late. KioM, the editor automatically packs all the contents of the folder you specified into an archive after it finishes working. If you mess up the contents of the folder while working on the map in the editor, you either need to make a backup copy of the map in the maps folder before the editor closes, or close it forcefully (e.g., through Task Manager).
