What happened? Big crevice is very close to my spawn-place on the left. Still left — very long line 1 chunk in width, from south-west to north-east. It runs through 3 biomes. In the end of line is jungle, but around the jungle is desert!
This strange fact was found by me on new «fresh»-generated map. Seed — 130893antonio. Just look at this screenshots and say what can it be?..
So, it’s just new MC version, nothing hasn’t bugs. I believe it will be fixed soon. And I hope this screenshots/map shall help Mojang.
P.S. I assure you that I did not use any map editors. But, unfortunately, I cannot approve this.
