Hmm, I'll take closer look when I get home, but I'll be sure to add it asap if it's gone! :)
Thanks for getting back to me! Do you mean in the sample images? There is no image that has 22 rows in the tileset. And yes, the corner piece exists in the samples, but it is not in the correct 16x16 format there. I tried extracting it, but it seems slightly angled. Or do you mean something else? Would you be able to point it out in another way, perhaps by file name? Maybe I am looking in the wrong spot entirely.
