Thanks for getting back to this! As of version 1.7, this has not occurred. Things seem to be okay at the moment. I will report any deletion issues if they happen again. Thanks again for your time!

Update*: This problem continues. Every world (4 so far now) that I've created since this update has vanished. Each time using different seeds, (survival, no experimental gameplay) with varied progression. However worlds that were made PRE 1.5 that I've accessed since the latest update remain on the list. There appears to be more and more similar issues being reported related to power outages, and turning the xbox completely off, versus standby or "sleep" mode. Most people do this in order to conserve electricity, or to protect fragile electronics from stormy weather (which happens a lot where I live), or to simply cut down on temperature because these xbox power sources are like portable furnaces. Nevertheless, this seems to be the issue at hand here. It's just so odd how it just vanishes though. I mean, I get how disabling power every night severs that connection to Xbox Live, so your data can't be synced or updated during that time, hence why you check for daily updates. But for not just one, but multiple worlds to just disappear without a trace is just beyond me.

Like Todd above, I have also attempted conversion again. Same issue persists. Still holding out hope. But that's the beauty of this game. It's highly unforgiving when things go wrong (For instance, getting pummeled by ghast fire, and then falling through the ground into a sea of lava with all your best gear while auto save is on, rookie mistake I know.), yet influences you to start fresh over and over. So you get to re-live those new beginnings. Refreshing for some, an annoyance to others. Back to the subject at hand. As previously stated in another comment of mine, my world is roughly 280MB. I also tested a 9.4MB creative "classic" sized map. The large file crashed exactly as before. Hit somewhere within 80-90%, crashed, forced me to hard reset the console (XB1). The smaller file quickly reached within 40%, crashed the game too, but managed to not freeze the console, and safely returned to the home page. Still perplexed as to what exactly is going on at 80-90%. The beginning stages (0-50% if its large, 0-20% if small) seem to go by rather quickly at times, but once halfway through, i notice a slow down. Shortly after, once (80-90% for Large, 35-40% for Small) hits, it's "game over". I also have come to understand that some players have managed to convert their worlds, only to have their builds destroyed, or cut in half. Landscapes marred with new generation, etc. This worries me, as this has been a battle upon release. How fun would that be after all these attempts? Still, it's giving me time to figure out the mechanics, how this version acts compared to the old, etc, etc. So, uh...thanks? :]

I have this same issue. My Xbox One Edition world, large size, is roughly 285MB. I'm assuming it's due to the fact that I have explored 22/25 maps. But, I've only really built within the center 9x9 area. Nothing too extreme really. Began on the 360, in 2014. Transferred world to XB1 in 2015, expanded it. And now here we are. Every time I attempt conversion, this is even after the recent 1.2.1 update, it gets to about 84% complete and crashes. It renders my console to a virtually useless state, until I reset it. Every single time. I'm wondering at what point in the process is the crash happening..is it the conversion of chests, redstone, and all aesthetic blocks? Or is it the memorization of the player's inventory, tamed animals, and other entities? What a mystery it is! Even tried a "classic sized map" I think it was only 19MB, very small. Failed and crashed at roughly 64%. It's a bummer that I might have to start fresh, but I understand this is probably a very difficult fix. Transfer from 360 to the One was easy enough, they were essentially the exact same game to their core. But this "Better Together" version was started from scratch I've heard, so even though it's the same game..it's not? I must research more! Keep at it, Mojang team. You got this!
