After installing the update that gives a halloween background, I loaded up my world and it was very laggy so I relaunched Minecraft hoping that would help, loaded up the world again, once in the world it would be fine for 10-15 seconds and then the screen would freeze and the game would crash and I would be sent back to the xbox home page. This keeps happening after restarting console, after creating a copy of the world and loading that etc. 

Please see to this issue as I've seen others talk about it.
