No one has said the programmers are doing it the smart, optimized way. As I said, the evidence points to them doing a "nearest neighbors" calculation for each and every block, perhaps not even checking "path to ground" for a given block, but instead calculating based on every block in the build, for every block in the build.

To test this, go make a simple house, then add 45 degree beams off the roofline until it collapses. Notice that it takes several seconds for the system to decide that last beam needs to fall off.
