Thanks for your response. I was using the ones specifically marked cascades from the pool/pond/fountain section. I read the descriptions as well to be positive. The fountain also does not work. There is no water movement at all from this kit. All of my other water features work normally. I own every expansion, pack, and kit and all the rest are fine.
In Walls down mode the big rock does indeed disappear. The small one are still there. in cut away and walls up the big one is visible and water flows for the small one this is true even in walls down view.
