Bit of an odd one, couldn't find any related issues upon search, so looks like I'm making a new report! Since the latest update, I have attempted to start fresh in a new world twice now. Everything goes really well, loads fine, operates efficiently. And this will go on for days, working fine each time I play. But for some reason, almost if out of the blue, I'll go to turn my xbox on, load up Minecraft, and the new world which I have created and named will be gone from the list. Just vanished, not in the cloud, nowhere to be found. (Should've made a copy). Now, when I turn my console off at night, I turn it full off. No sleep mode. So it basically gets a hard reset daily. I thought that this might have something to do with it, but the world in question never comes back. There doesn't seem to any confusion between my xbox live (online) data and offline data, so I have absolutely no clue what's going on. I don't even want to load old worlds in fear that the curse might fall unto them as well. This has only affected two newly created worlds so far. I will start a third, to see if it happens again.
