Details of the issue:

I was playing normally and one Day when i tried opening up my world i got an error saying that the backup level.dat is being used.
I made a backup and hit play anyway, then my ftb crashed.
i kinda let this world sit for a while until the 2.5.3 Update, when i tried to open it then i got a message showing that some blocks were missing, i clicked on play and at that point the game just crashes, this is not happening for any other Worlds.
I hope someone can help, since i put a lot of time into this World.​
