Today I decided to go on Minecraft Windows 10 edition only to find that skin had disappeared. When I tried to put my skin back on, it said "This is not a minecraft skin, silly." I've been using the skin a long time, so I don't know what's going on there. Also, I checked my worlds, and all of them had disappeared (Both multiplayer and single player). I minecraftWorlds folder and all of my worlds were there, but didn't show up on my worlds menu. Thanks for reviewing.
