Minecraft keeps freezing

New minecraft game for xbox 360 keeps freezing at the game screen?

My xbox keeps freezing and freezing and idk if it's cuz my world is to big for minecraft (19MB) or if it's cuz my xbox is really hot but ever sens the new update for minecraft came out it just keeps freezing as soon as I go into the world the first 2 minutes
are ok but then it freezes I have my xbox in the freezer right now cooling down and I'll try to delete some minecraft things but all I know is notch or 4j studios needs to fix this fast cuz I have a important server I'm running and I can't get it running if
this keeps freezing I have found a little something that helps if you go into your game save right away and move a little then save do this about 10 times and it should not freeze but keep saving ever once awhile

For me, on my Xbox 360, I have a whole bunch of other worlds, and they all work, but my favourite world (of course) doesn't work. When I try to enter it, it gets to the loading point where it says initializing server, then it freezes, and I have to refresh
(turn off and turn back on) my Xbox. It's very annoying. I need, help, because I really love that world D:

every time i go to my old world its so laggy an buggie ever seens the 1.8.2 came out what the heck 4j >_<

mine keeps freezing too. It only happens on the minecraft game because i play all my other games and it doesn't happen, does anyone know what the hell is wrong with the minecraft game?
