I use custom static objects (Walls) of my custom story folder. You know I have to use it from there, otherwise others can't play my map.
Suddenly when I open the Level Editor, the walls change to different things, such as stairs from the castle.
So I searched for the problem. This didn't help:
Now I made a folder in entities I named it custom_ents. In the folder are all of my entities. Then I changed the MainEditorSettings.cfg by replacing the text of what you said. Then I restart my editor and changed the static_objects to normal and saved it. Then I restarted the editor again, this time I have no error but the static_objects are changed again.
