Realm of Mianite server Suddenly dead?

[Punti]

Hey,

i started playing Realm of Mianite with two mates and suddenly i can't start the server anymore. The Server did not Crash the last time we played it just suddenly didn't start up anymore.
Server log is attached. The last things we used before the Server didn't work anymore: Chisel,Quarry,Ender Tank

[FML/]: Forge Mod Loader detected that the backup level.dat is being used.

This may happen due to a bug or corruption, continuing can damage
your world beyond repair or lose data / progress.

It's recommended to create a world backup before continuing.

make a backup, and type fml /comfirm when it prompts you and see if it gets past the issue.

So i copied and pasted the world folder, started the server up and typed /fml confirm after the error but it just shows the same error again and asks me too type /fml confirm or /fml cancel again
