Please help me; my Minecraft world is corrupted, chunks are separated by oceans, and mobs aren't spawning. I tried level.dat.backup, but my compass kept leading me to the middle of the ocean. If anyone can fix this for me, here are the level.dat files:
level.dat.backup: http://www.mediafire.com/download/h92nmkrlzbxqo2m/level.dat.backup
level.dat_old: http://www.mediafire.com/download/ubtxgt3nmsiwvw9/level.dat_old
level.dat_mcr: http://www.mediafire.com/download/4h1ngvt336zb1hh/level.dat_mcr
session.lock: http://www.mediafire.com/download/uzom31wifkt18lb/session.lock
I will tell you nice and slow since you apparently didn't read it on the mod pages...
back...up...your...worlds
The only way to fix this is to delete the world...
