Issue description
Normal:

Pillar 'spots' are still there, even after removing the reason for their existence

If you try to drag another belt across, it places pillars in the same spots again

This is frustrating when you're trying to remove as many pillars as possible to have your build look clean, though it might be like this on purpose?
