Haven't taken a look at the cave fixes yet. Here to report some more in Snow Town, but mainly misuse of a cliff tile in paths.
Some more east of Sardon's
More corner issues to add.
All makes me wonder why anyone even bothered to write over my cliff tiling anyway. It's like no matter how many errors I discover, more and more appear.
Also to add, I'm still seeing the graal-cliffs-18.png error.
