The glitch I encountered on my xbox is something I have never seen on my xbox, on any other xboxs' in my house, and even on YouTube! Many things happened on this world. This was all in a world I created on xbox 1 version on minecraft. I had just started a tutorial world, not because I'm new, but I'm too lazy to build. Anyways, I wondered around the tutorial world and nothing seemed off. I spent a 2 days on this world in real time, messing with the villagers, making random contraptions with the provided redstone and even had a friend on to help me build minecart track around the main area. Half way through the building process, he leaves, leaving me to do the rest of the work. Needless to say, I got bored quickly. As I left my world on, I watched a few episodes of "Scream", and even watched through half a movie. (As stated) I stopped half way through the movie to see my player being attacked. Just as it started, I grabbed my controller, rebooted it, and died before I could fight off the opposer. I quickly ran back to pick up my stuff to see (out of all the hostile things in minecraft) wolves around my stuff. I grabbed all my stuff and continued through my world and started to notice the little things such as the cows on the top of the mountain were gone, there was only 1 sheep in the area, bones were everywhere along with wool. When I found out all these things, it was in-game night and I went to bed. When I woke up (in-game) I went to the farm to see that wolves have replaced the sheep, chickens, and even the cows in captivity. The wolves were all just blankly staring at me. Except 1. I looked over to the actual fence area of the wolves to see 1 wolf, normal looking at first the twitching with the occasional flashing red eyes that mostly worked vice versa with the twitching.
