If you place your whole inventory of light objects like food and utensils then all your armor...so you drop 500 lb of stuff in a shop, then throw a power 1 range 100 fireball and the game will overload.
Just try not to have a ton going on at once. What is supposed to happen, the Xbox can handle.
Yeah, don't try to duplicate too much at once or it will keep freezing constantly on you.
