The house of inn at the lake in the 6th expansion is the same one which they use for the pig farm. It is only mirrored.
Well that's very unfortunate. All the other inn buildings are identical, but this one looks like just a plain, decorative farmhouse. (It's not just a color change; the whole style is different.)

One of these things is not like the others; one of these things just doesn't belong... ♫
The yellow color makes it blend into the tile background more, and given how yellow buildings are used elsewhere it generally communicates "this thing is just for decoration; ignore it." Of course veterans will know it is supposed to be an offical inn by comparing to the Carcassonne 1.0 version of the same tile ... but allowing aesthetic indulgence at the expense of gameplay clarity is never a good design choice. The CAR 2.0 will require a clarification that this tile does indeed contain an Inn even though it doesn't look like one.
2.0 land seems filled with many weak decisions. Apparently HiG does not remember the lessons that have already been learned (:ahem: pig-herds).
