oh, I understand now.

Firstly, OpenStreetMap is not connected to Google Maps. So, an update on OpenStreetMap will not correct Google Maps.

Secondly, www.craterre.org does locate Villefontaine local site at Maison Levrat, very near Rue de la Buthière. I updated OpenStreetMap to show Maison Levrat. 

Did Craterre move to Les Grands Ateliers, Boulevard de Villefontaine, Villefontaine ?
