Cliff Texture on Flat Ground

Since the Mistlands update anytime I level ground on an already existing "levelled ground" boundary (where levelled ground and grass meet) the texture is replaced by cliff texture.

A non-issue unless you want to turn that ground into cultivated ground, you cannot cultivate that ground, you can cultivate it by cultivating the ground around it, and it will turn the texture green. This can be planted on but does not look good.

You cannot raise or lower the ground to remove the texture, it follows however high or low you create the ground.

You can use the cultivator to replace the grass and it will cover the texture and look like normal grass.
