I went back and updated the Lonesome Forest to get it more in line with other sets in this series. You'll find an alternated Cliff Walls that includes the floors baked into them (the original Cliff Walls with no floors is still included) and the River Shorline and Cobblestone Paths expanded into complete 47-tile sets. The River tiles can now serve as an excellent shoreline for larger bodies of water, so you no longer need to use Cliff Walls as your only way to outline your lakes and oceans in you game! 

And of course, this updates both the Summer and Winter versions of this set :)

Enjoy!
