Problem with the editor

[jch02140]

I tried to load a saved game generated from my own private server into the editor. Everything seems to be running fine, however, when I switch to editor mode with F8, the framerate drop to an abysmal 2~4 fps. However, when I turn off editor mode, the frame rate goes back up to normal again. Wondering if there is a way to fix it?

Also, how do I spawn enemies in editor mode?

Normally you are not supposed to edit the map when all of the world assets are generated. As you are not editing the map, but an actual save with millions of objects. So, obviously the editor is not able to handle all that.
You should only edit the map, not the generated game world.
