Description of the problem:
1.Yesterday my game just started randomly crashing for no aparent reason I had even left it just minimized while my inventory is open and it crashed like 5 mins after).
2.The bigger problem is today my creative world (which is 1 month old) shows up in the menu but my main doesn't. So I redownloaded everything and when I put the world in the folder and click Single PLayer the game throws the second crash report I liked above (but it doesnt close or anything it works fine) but when I put the world back in the "saves" folder, click "back" and the "Single Player" there isnt anything new in the console. IDK what caused it, I was playing on 1.0.14 since it came out so it shouldn't be the problem.

Thanks in advance and BTW:

P.S: Even my 1 week old backup throws the same error...
P.P.S: Even with the recomended version.....

Never mind, I "fixed" it. It seems that my level.dat got corrupted (even in the old save WTF? ) but for anyone wondering how to fix it:
Keep in mind it is going to wipe your player date (i.e inventory,position and etc.)
1.Make a new world
2.Enter the world and leave
3.Go to your saves folder of that particular pack
4.Copy your level.dat FROM the new world TO the old world and replace it.
5.Delete the new world.
6.Enter the old one and go to Cheat Mode on NEI and give your items back.
