Event Hook's Not Being Used Serverside

[Zetal]

So I've been writing a mod almost non-stop for the past few days, and for some reason the server doesn't seem to be going through the events I have, but the client does. Isn't it supposed to be interlaced, now? What's the deal?

 

(In my main class)

     @ServerStarting
     public void serverStart(FMLServerStartingEvent event)
     {
    	server = event.getServer();
    	processor = DataHandler.getProcessor();
MinecraftForge.EVENT_BUS.register(new EventHookContainerClass());
        ServerCommandManager scm = (ServerCommandManager)event.getServer().getCommandManager();
        scm.registerCommand(new CommandCreateShape());
        scm.registerCommand(new CommandCreatePolyzone());
     }

 

(In my event handler)

        @ForgeSubscribe
        public void onEntityMove(LivingUpdateEvent event)
        {        	        
if(event.entity instanceof EntityPlayer || event.entity instanceof EntityPlayerMP)
    	{
    			EntityPlayer player = (EntityPlayer) event.entity;
        	if(((int)(player.posY - player.getEyeHeight()) == (int)player.posY))
        	{
	        	if(PolyZones.processor.getPlayer(((EntityPlayer)event.entity).username) == null)
	        	{
	        		if(Side.CLIENT.isClient())
	        		{
	        			System.out.println("I'm a client!");
	        		}
	        		if(Side.SERVER.isServer())
	        		{
	        			System.out.println("I'm a server!");
	        		}
		        	PolyZones.processor.addPlayer((EntityPlayer)event.entity);
        			player.sendChatToPlayer("Added new CustomPlayer " + PolyZones.processor.getPlayer(player.username).getName());
	        	}
                   }
}
}

 

 

Any help is appreciated. Thank you!
