Problem: user wants to share a route from A to B,
but Grasshopper does not know about the new roads on OSM,
and in fact knows about roads that have already been removed from OSM,
and there is no "refresh Grasshopper’s knowledge of the region in view’ button.
Library proper name is GraphHopper.
Grasshopper is something different! 
There won’t be something like this. The update process will always take days or at least hours.
