Removed a few mods, now I can't load my world

[Flenix]

Hey guys,

 

My server was having crashing issues, so I removed some mods to see if it fixed it.

Now, I can't load my existing world (Although I can create a new one... but we have a LOT in that existing world)

 

Anyone got any ideas? Here's the (pretty useless) stacktrace:
