In Minecraft PE all year, despite always updating, whenever we break blocks they take forever to appear and can't be picked up. When we go in water the character walks instead of swims. If we fall from a high place it takes a long time for the damage to be applied. Also, if we choose to save external the game won't even load. In previous years save external, and all of the above, worked fine.
