Hey, there is a bug I have spotted within the component construction where occasionally if you are creating a shape and remove some sand, the design looks correct. However, once creation begins, the shape changes and extra sand is removed or some sand is added. This means you make the wrong shape and use up resources. However, to bypass this, tapping slowly works 4/5 times. Just bringing it up as many people used up gold and iron that I had been gathering because of it.
