Losing worlds after game get closed

FIXED

May appear in other versions

When you first start everything is fine - the game works as it should. But if you close and reopen Minecraft, then all settings are reset, worlds are deleted, and you log out of your Xbox Live account. It is the deleting, not just disappearance of the worlds, because after reopening the game, those were completely lost.

I assume that the bug is caused by moving the worlds to a new storage folder.

Edited: Step-by-step instruction for causing this bug:

1) Open Minecraft, create a world

2) Save and quit world

3) Quit from Minecraft

4) Open Minecraft again

5) Done. No worlds found.

 

EDITED 2: it self-fixed somehow lmao

I suppose that bug also could be caused by moving Minecraft to external memory (SD-card).

But there is still a question: if bug got self-fixed, then... where is my grand railroad station?
