My mod works fine when running on the client, but if I try to start a server with it installed I get this error.

2013-06-11 14:17:39 [sEVERE] [Minecraft-Server] This crash report has been saved to: C:\Users\John\Desktop\Games\Programming\Minecraft\forge\mcp\jars\.\crash-reports\crash-2013-06-11_14.17.39-server.txt

 

 

 

At the line 99 it's talking  about I'm doing

MinecraftForge.EVENT_BUS.register(new EventHookClass());

 

Any help would be greatly appreciated, everything is working correctly when debugging on the client and this is the only bug keeping the mod from being playable.

 

UPDATE

May have jumped the gun a bit with that, I'm 99% sure WorldClient is trying to be used but I can't find where

    For archive purposes, it turns out I was accessing the world object improperly in my HockClass:

    Minecraft.getMinecraft().theWorld

    In an PlayerInteractEvent event it should be:

    playerInteractEvent.entityPlayer.worldObj

    It's probably very similar for other events.
