the floor tiles were added to the tileset by mateus when he worked for us like 3 years ago. sorry we didnt pick up on it, but we dont have that much free time on our hands to reference everything our gfx artists make. and considering the fact that mateus was a talented gfx artist, i dont think anyone thought anything of it.
p.s. glad u all like my gfx work and spar arena
