So I spend hours and hours designing and creating worlds with my friends, we have over 300 worlds we have made in the past year and we put so much time and effort into them. I go to log in and load up our most recent project to find it completely gone, the whole world generation deleted everything within a 500 block radius of spawn completely deleting all of our work. and when I go into any other worlds they have the exact same problems. all that hard work just for one little Minecraft bug to completely destroy months of work in every world I have, oh but don't worry there's goats in the game now YEPEE!! Like OMG Mojang if your gonna upgrade the games mechanics so the game stays popular then fine i don't care but make sure it doesn't screw over the most basic of Minecraft functionality and completely ruin the game for people who actually love the game for what it is. :'(
