I'm running a custom instance of Wikibase with SPARQL service and I'd noticed that updater service  (runUpdate.sh) doesn't really update triplestore with new properties created in my Wikibase instance.  As well as I can see, newly created P-item names aren't even returned by API call for "recentchanges". So new properties with their names and other attributes never appear in the triplestore after their creation.   

Once the property is used in some statement or qualifier, corresponding triples are put into the triplestore immediately, but the property remains without names or descriptions.

Is it because properties are managed centrally in Wikidata? Is it assumed that I should reload a full snapshot each time I create a new property? Or is it some bug on my side?

Thank you for your help!
