I feel you mate, I remember a year or so ago, I got an update for Minecraft X-Box 360 Edition, and the place where I was situated (my village) became the new North Pole and the entire ocean in the world was just a giant chunk of ice. I adapted to it, but it's still very strange since it never happened before in previous updates and my place was on a beach with a densely wooded forest near it. Plus there was only one spruce wood tree that spawned within my world naturally that I got 3 saplings from, so it was beyond strange.
