Problem Server keeps crashing on startup

[Snayler0]

Hey guys.

So i spent about 4 hours last night messing around on my server. After an unexpected shutdown I am getting the attached error on startup and the server wont start anymore.

So the world has some sort of corruption... is there any way to recover?

Any help would be much appreciated!

You could try removing thaumcraft, then restart the server then stop it and readd thaumcraft back. that is the only mod that I could find the name of in the file... you will lose anything already placed but you could get your world back.
