Parts of my house float in the air after I remove one block

You take away a pillar and the roof stays up, or two hanging beams hold each other forever. This entry gives your AI a support check that finds every piece that has no real way down to the ground, including pieces that only hold each other.

Why this works

Support is a chain that must end at the ground. Starting from the ground and spreading outward marks everything that is held, so whatever stays unmarked, including loops that hold only each other, must fall.

When not to use it

If floating buildings are a feature, such as sky islands, skip the check for those areas or mark them as anchored.
