[Draco18s]

You're using client-only code in common code.  Specifically you are calling

Display.setTitle("Minecraft - 1.10.2 | DeGeweldigeMod - " + Reference.VERSION);

 

You should not be doing this at all ever.

[Choonster]

From your previous thread:

  Quote

Using rendering-related classes like

Display

in common code will crash the dedicated server since it doesn't use those libraries. Rendering-related code must only run on the client side. Changing the window title is a bit obnoxious, the user doesn't need to be constantly reminded that they're using your mod.

[Egietje]

Thanks!

It works now
