The Ukraine tile was released by HiG in 2022. This limited promo tile was available for the fair in Essen and remainders were sold on the CundCo webshop. The sales proceeds and more go to the NGO Come Back Alive. There are no special rules. You can use it as a normal tile, as an additional tile for the 1st expansion Exp. 1 - Inns & Cathedrals, where it can be used as an inn, and/or as an additional tile for the Mini 7 - The Crop Circles. The white building by the lake represents a traditional Ukranian house, that may serve as an inn in the game.
