Coastal Bluffs terrain and texture mismatch (invisible ramp)

In Coastal Bluffs, on the small island in the northeast, there is an invisible "ramp" of terrain on a rock formation. This ramp does not match the textures, and can cause some creatures to bounce up and down.

Creature can smoothly walk up an invisible ramp on the side of a rock formation, leading them to a natural shelf.

Creature should not be able to walk up the observable terrain / the terrain and textures should better align.
