So one of my oldest words keeps crashing after 30 seconds, the world was working find up until a random crash. Then I used one of the backs ups, which after building stuff it crashed again. The worlds can't be saved because it it kicks you to the home page and, you can do what ever you want In the worlds but only for 30 seconds and then it crashes, it does save but it crashes. And you can't play any other game unless you restart the Xbox 

Added: all the back up as well keeps crashing, and even though they are older the the main one which crashed, and the worlds are unplayable. The screen freezes and take you to the home page. It saves what happened but it keeps repeating it. It happens all over the world not just in one place, the game freezes and then kicks you to the home page

You can build stuff on there for the 30 seconds, but it’s very laggy and when it crashes it does save but the you have to restart if you want to play anything else or eve play another world
