So I'm been seeing some formations just floating in the air, so far I'm mostly been seeing them in birch forest. I think it may have something to do with the Y coordinates for the mountain forming and some air underneath, but Idk... please fix this as soon as possible. ...also Jeb, if you're reading this I'm a BIG fan of minecraft, I'm been playing for almost 11 years, and maybe one day I'll go to Sweden and help with the development, thank you for talking the time for reading this, goodbye.
