So, somehow, i accidentally deleted my cliff tiles and i have no cliffs to place. Id rather not wipe the terrain set and re-do it because I already had a large chunk of nice terrain made (close to a 128x128 map) and I'd rather not re-do it. Is there a way to re-add cliff tiles via the "Add Tiles" section of Grimiore under "Extensions" or do I have to re-do it?
