I was the person who initially tiled those big mountains, so I know cliff tiling (albeit this is a different tileset so I'm not impervious to error). Also, I've had training in wildlife tracking.
Anyway, here's another error south of Swamp Town.
And... another one near that unresolved northface shadow.
Another northface shadow error right at Delta Island cave entrance.
Adding this next one. I don't consider it an egregious tile error, and I haven't really been reporting this kind of error where it's hard to avoid it. But when I'm done finding the really bad ones, I'll start reporting more of this type, which might possibly be only fixable via additional graphics.
