I did launch the game once while I had this level loaded in the editor, but when I saw the warning I closed the editor right away and haven't had them both open at the same time since then. Is it likely that the level became corrupted during that time? If so, is there some way to reset or refresh the level somehow or do I just need to start over?
Also I figured out the fog problem, I had just set another atmosphere in DM mode and forgotten about that.
