Combining buildings error

Trying to build a foundation, and have part of my building disappearing when connected to other buildings. Then, if you try to remove it, it won’t remove.

Paging @albert, have you see this one before? Is this an issue with the building AI trying to combine buildings?

Yep. looks like a bug in the code combining buildings.
