Current questions and answers regarding the map editor.

Hello, is it normal that the editor just deletes files with DialogScene scenes? Yesterday, I created two scenes, and today I planned to continue working on them, but not only did it delete index.bin (which is already a tradition with this terrible editor) from the map folder, but now I also found that it deleted the folders with the scene files. Does this happen after some action? Or is the editor so bad that it does this completely randomly? I'm using the editor for Tribes of the East.
