Massive glitches throughout my game, I loaded up 1.9 for the first time and began a new world. Every time I moved my mouse the blocks changed while the animals stayed the same like they were in the actual world I was supposed to be in. I tried loading up a new world, thinking having game mode cheats on was the problem. Turns out, the same thing happened and I haven't been able to find a cure for this. Please help!
