I took some self-similar crescents in my map to give it few extra dimensions. I just lower the crescent's size to 10%. In the Inkscape is everything precise, but in the Warlight attack the nails. The 2nd dimension is clear, but in the 3rd dimension some small nails show up, and in the 4th dimension more big nails attack.
It is possible to remove the nails? Not a too big problem, just if the nails are removable then I remove them.
