Carcassonne: Corn Circles IIExpansion

From BoardGameGeek:

Carcassonne: Die Kornkreise II (The Corn Circles II/The Crop Circles II), is the seventh official mini-expansion for Carcassonne. A corn circle tile allows a player to place a second follower on a feature that they have already claimed, or to return an already-placed follower to his supply. One of the six tiles of Carcassonne: Die Kornkreise II comes packaged with each of the other 6 mini expansions. Each of the mini expansions contains one part for the corn circles. The rules are the same as Carcassonne: Die Kornkreise, but the tiles have different layouts. Part of the Carcassonne series.
