[1.10.2] [Solved] Mod crashes server

Erfurt · November 30, 2016

Hey guys, so I'm trying to get my mod onto a server for my friends and I. But it doesn't work. I have tried running it in eclipse's server thingy, and I got this error/crash message, I'm hoping someone could look at it, and maybe give me some directions on what to look at/change in my code to make my mod work on a server. I should mention that the mod is working fine on client side.

The reason why I want someone to look at it, is because I can't seem to figure out what is wrong. (Kinda obvious )

Error/crash message
