For the past couple of days I play then I get disc is unreadable and to clean with a soft cloth. Problem is, is its a digital download. It usually only happens after a weekly update. Now is happening more often when it wasn't before. This is a great game but the problems are becoming exasperating. I can reinstall the game a hundred times and I doubt it'll change anything. Not had one of the animals attack me for a bit. This doesn't even have a error code name. Just kicks to 360 home screen and forces me to restart the game from the dash board.
