I was playing minecraft with mods installed (168 mods I think) suddenly my minecraft crashed , I restarted minecraft but now the world is missing, it is still in the saves folder but not in minecraft anymore, I tried to make a new world and replace the level.dat, level.dat_mcr, level.dat_old and session.lock like shown in a tutorial to recover corrupt worlds, but it didn't work as the world was still not showing up in minecraft. I can still open my world in mcedit, but how can I fix this problem? Please help.
