This append twice in the last month with two different worlds in Minecraft on Xbox (minecraft bedrock edition). The world I was playing on one day doesn't appeared in the menu the next day. My xbox is connected to internet and it seems to sync my data with the cloud all the time. I tried to recover the data by going to the menu "manage game" but the data is not there. It does not affect all my saved world just the last one I was playing on (e.i. the most advanced). And it's not appending all the time, just one day the world is not there anymore.
Can someone Help me with this problem ? Will it help to re-install the game hoping that something is wrong with the game itself ?
