Non-support blocks (such as crucibles) can be built underneath other blocks. Since non-support blocks having blocks above them is invalid, this needs to be fixed. This could be tricky in the case of multi-tile non-support structures, such as Obelisks, which are technically allowed to have blocks above the base tile since their construction calls for it.
