After this patch, the game has become more glitchy when loading chunks, and the developers have changed how the minecraft xbox signs work, where the keyboard covers the majority of the screen. The sign change, makes it imparatical to write any signs, this issue is with many people and therefore I consider this to be a bug, which needs to be fixed. 

More information about the signs, it is diffuclt to use commands, as the text is deleted, when writing a sign again the 4th layer is deleted. With the signs you can not see what you are writing on the sign, and therefore, it is difficult to know when you have written too much on one layer.
