PS3 battle minigame map not loading??

i have had ps3 edition minecraft for a long time now, over a year perhaps? my disc is quite scratched, but whenever i try and join a battle minigame, everything works until the battle itself begins, which is when the world is just an endless void of blue with a couple of players in it, who can see what theyre doing. and if i try to create my own minigame, when the battle is about to start it just says 'waiting for data to load', and it doesnt load at all. if this issue can be resolved that would be helpful because i dont really want to spend another £20 on a new mc disc. unfortunately i do not have any screenshots or pictures.
