I just went into the snapshot and noticed only one issue generating. When I went into the Giza Plateau, last night. I ran into a issue. I am assuming your trying to make canyons in minecraft. The problem is you go to the Stone area and then see blocks above you. I do not see a canyon but see the land at the top. Under neath is nothing but stone. under neath but I do see the grass. I googled Giza Plateau and seen your trying to make a canyon of some kind. Your not generating a Canyon. I went into nothing but Stone underneath in the world I was in. I am posting a video if you want to see what I found but I forgot to do the seed at the time. I will be testing this but there is a serious world generation with this. I have been in the hospital for two days to be able to thoroughly investigate this issue. I will update this blog in a few hours and try to recreate what I found. If anyone is having this sort of issue please comment below this ticket so Jeb and them can get a working seed so they can see this first hand, please. I am going to try and get you a seed so you can get this as well. PV
