Did not try the 5x5, but the footprint (that little green dot in the planning window) is far outside and away from the actual displayed footprint of the 5x10 and 5x15 of the Stone Floor Wishbone and Decorative. On the 5x10 it seems to be about 10m away from the nearest corner, and 15 or 20m distant on the 5x15 - as if it is using the footprint for a larger object. Currently it makes these unusable.

Nice thing about these two styles - they are thicker and so can hide places where the ground isn't perfectly flat whereas the thinner stone floorings 'disappear' and leave gaps even with 1 and 2 pixel differences in ground level. (Even if they do use tremendous amounts of resources compared to their thinner varieties).
