Yeah, i was pretty sure of that ^^ But hills & sheep being the last expansion of old artwork, it did'nt stay long in France. As far as I remember, i did'nt see any of this box for more than a year in France.
But don't dispair, if you buy the big big 5, you'll get River 3 which is a nice addition to Hills & Sheep, some more meeples, and you'll be able to offer the base game AND some expansions to somebody, wouldn’t that be nice ?
