Awesome Minecraft World Crashing

Thanks for the response, but the world wasn’t created in the beta. We moved it to the beta to see new stuff and it has been working all week until yesterday.

I've been having this happen to me too lately.

Hey there! So the beta version available through the Xbox Insiders Program is very liable to crash. The best thing to do if you are running and experiencing stability issues (something that is lined up in the FAQ about that version in the XIP app) would
be to fill out a ticket/feedback/report in the app or directly on Minecraft's website. When you load up the game and see that world pay close attention to the file size, in my experience with that in-progress-build of Minecraft world saves over or around 150
to 200 mbs (megabytes) tend to crash. Naturally the problem will ride itself out whenever the game updates or there is an update to the build being ran. Don't try and de-enroll that world/game version out of the beta as any worlds running beta content (for
example yours since you moved it up) wouldn't be playable until the next update. I would just keep trying and send in a support ticket where appropriate.

Thanks a lot for the reply! The world is about 148 megabytes and so I see why it's failing. Thanks for sharing what I can do by waiting until the version comes out fully. Thanks!

This issue seem to have several reasons one of them being when you try to convert a beta created world into the xbox one edition . I suggest you to post regarding this in-game issue at the game devs forums.
