settlement decorations can break continuous logic, with the shift move

1. Place settlement decoration.
2. Place 2nd settlement decoration.
3. Shift place 2nd settlement decoration, to a new location.
4. Place a 3rd settlement decoration, in the same yellow grid as the first.

Game logic is now broken, preventing deconstruction of anything connected to that grid. Even sandbox removing the ground under it, cant remove it.

Shift moving, happen to be same button, as mass placing, so this can happen by accident.
