Updated 6 card files

There was a small error in the 6 cards per page files of Grimm World. The front and backside of the Terrain Card 22 and 23 were switched. This is no problem, if you already printed it in duplex, because these two cards are always used together in a combat. So you will not notice it, but it is now fixed with this new version.
Sorry for that and have fun with the game.
