A crash while playing a world

Hi mojang. Im just playing minecraft beta on my xbox, while i was creating a world and playing it. The 10 minutes i was crafting something. Then the game freezes and i thought it was a lag. But no. The game has crash. I think yall need to check the beta minecraft for the xbox. Because it seems to be a crash. And is not the world i checked other worlds but is the same thing. Please fix it until yall make an update.please.
