Wilds Unknown out of print

According to the manager of our local Ravensburger Store here in germany, Wilds Unknown seems to be out of print. This information comes directly from her. She tried to reorder all products from Ravensburger’s central warehouse, but was informed that no further stock would be arriving. While this is not an official public announcement, it is the information she received directly through Ravensburger’s distribution channels. Thoughts on this? Could this really be true?
