Look at the Test play window and the edit..
Why there's a roof there?? Can anyone help me out  :dead:

I think you possibly accidentally placed a roof autotile in a lower layer, but due to its priority, it appeared in front of the other roof. Check that.
Ciao!

Sage or Horses is right- the roofing autotile has priority over the outer roof tiles. The solution- just don't use the roof autotile there.

And if you can't see it hit F4. (When not on the event layer.)
