You missed one that I posted (albeit you fixed the more obvious error from the same screenshot). Here are some more, this time with more annotation.
In graal-cliffs-14.png, I'm not so sure whether to call the middle circle a tile error. I never really tiled that style of cliff junctions because it always looked like a massive tile error to do them that way. I neglected to annotate similar cliff junctions.
Also, you might just want to temporarily change your tileset to make the dirt-cliff-edge tile a solid red square when editing so it's easier to identify where that mistake is. There are stray uses of it all over Snow Town.
