Hello, I´m making some tests with the level editor, but I can´t figure out how to use the window doodads backgroundwindowstone and factory.
I can place them on the map ok, but when I hit test they disappear behind the stone/factory background. I tried deleting the background tiles behind them but then I get blank spaces on the border of the windows. (if needed I can post screenshots)

Am I doing something wrong?

Thanks in advance.
