My implementation of indexing and aggregation was incorrect on child nodes, re-creating the child nodes from the root.

There was also another bug when indexing inherited coordinates that meant formerly inherited coordinates were incorrectly dropped from results.

re-creating the child nodes from the root.

Oh yeah classic - I've made this mistake in implementations before.
