If the building with an invalid structure is directly touching another building that has been already finished, it will only show you the notice that there are invalid parts to it, but nothing flashes.
Steps to reproduce:
- Make a random house and have it built.
- Place another house directly next to it, including an invalid design. (I use a door, that’s placed inside a wall just tall as the door and then place a few block on top of the door.)
- Click build on the new structure. It will warn you, but nothing’s going to indicate what’s wrong.
The tan block above the door start flashing red.
I don’t know what’s wrong and I can’t start building my house.
