Just Build, North America region, default map
Bug : The bug is that you can’t place carpet on top another carpet or a non-solid block. For instance, I was trying to build a cat area for my house. I was confused when I couldn’t place the carpet on another carpet, which I could do on a flat world. (Sorry if the links don’t work it’s hard on IOS. If the links don’t work test it out.)
IOS and 1.16
