same place
i assume they made sub divison not a "clone"
Subdivision isn't exactly the same as main division. It's rotated 90 degrees, so what is facing west in the main division is facing north in the subdivision, etc... Maybe these mirage houses are background objects that weren't rotated with the ward. They may have ended up in a different direction relative to the main division.
edit: Well, I just checked, and this one doesn't seem to just be a case of direction. Those houses in the background are situated to the southeast in the subdivision. In the main division, if you look southeast from the same spot, the view is still unobstructed, but still no houses.
I'm wondering if they either forget to place some of the backdrop layers, or placed them differently so draw distance isn't picking them up.
