This is going to be a bit complicated. I was playing on the Yogscast Complete Pack and recording a video. All of the sudden a box popped up and said launcher update, then my game shut down. I reloaded the instance, and my world has disappeared. When I look in my instance folder, my world is still there, but will not show up on the minecraft start up page?!? I've been recording a "Let's Play Series" on this map for the last few months and really don't want to start over! What can I do?
Also I looked in my saves folder and the only level.dat I have is level.dat_mcr. I don't have any of the other ones.
I don't know if this will work, but you COULD create a new world, close MC, then erase the contents of that world, replacing them with that from your own... I don't know if that will fix the issue, but its possible it may.
