Still having problems

Nice outhouse! Complete with ummm... biological layer. How authentic ‎ 

Something I wish I had done with my house set, and I think it might benefit your outhouse too, is to get rid of the "grass ground" border around the walls. If I had made the house Pieces just a little bigger than a regular map tile, they could have slightly overlapped the surrounded Pieces instead of needing the border. That would let people place it on many different surfaces without having to adjust the ground-border's texture or shape.

Probably the correct way is for the outer walls to line up with the edge of the tiles, with any eaves extending out over the edges.

EDITED: In fact. If tile sets don't work that way I would not host them on any website I am responsible for.
