Planning is broken when foundations built (foundations counting as walls)

[Alunny]

When I built my brick foundations my planning was completely ruined. There's whole segments gone because they were vertical lines which means now I have to guess where they were. The foundation is being counted as a wall every few blocks vertically....only the outside of the foundation should be.

Thanks for the input, I've logged a bug report against this now.

Sorry for that problem!
