What have I done now?
Nobody said the first rains. The timeline was within a year after the rains. That first water has percolated between the paving stones and is slowly starting to work its magic on the substrate, loosening the particles. It's the same way a pothole forms. Gradually.
Apparently this is 'normal'.
