Since I downloaded 1.5, minecraft has been a little buggy for me. It started to do this thing where it would just randomly close. So, I've been working really hard on this one world, and once again, it randomly shut me off. But now, whenever I try to open that world again, It pulls up that loading screen, freezes, and just sits there until I force quit it. It doesn't do this for any other world. I would just delete it and start over, but I've been working really hard and made a bunch of really cool buildings and I really don't want to!
Please help!
