It's is a issue that has lost me 2 of my worlds that me and my friends have worked on for over a year on and and were very important to us and we were very angry, and still are because we lost them with with no explanation or reason.

When I try to click on one of my worlds that have Been effected it starts to load the world but pauses at LOADING RESOURCES and eventually brings up that the world couldn't load and renders you unable to click on anything within the game
