Avis - Disappearance of GNB as a rental location?

I logged on to the Avis website today and tried to make a booking in France for next Feb. However I can no longer pick GNB (Grenoble-Isère Airport near Saint-Étienne-de-Saint-Geoirs).

I swear I could still pick this location on Monday when I last visited the site. Does anyone know anything about this location being withdrawn?

Many thanks.

Called up Avis and confrmed that this location only operates on a seasonal basis. Closed from end April to end Nov each year.
