Crash Exception in server tick loop

[codistyle]

I wanted to play a small Modpack with some friends on my Nitrado Server.

So I made the pack, works fine in Singleplayer. Then I tried to put it on the Server, and it doesen't even start.

It crashes every time and I can't figure out why from the crash report.
