[1.12.2] Replacing The Main Menu

У меня есть три класса.

RPGcore(MainClass) :

package ru.Morttal.RPGcore;

import org.apache.logging.log4j.Logger;


import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.SidedProxy;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import ru.Morttal.RPGcore.proxies.CommonProxy;

@Mod(
		   modid = RPGcore.MODID,
		   name = RPGcore.NAME,
		   version = RPGcore.VERSION,
		   clientSideOnly = RPGcore.clientSideOnly
		)
public class RPGcore {	
	   public static final String MODID = "rpgcore";
	   public static final String NAME = "RPGcore";
	   public static final String VERSION = "0.1.1";
	   public static final boolean clientSideOnly = true;
	   public static Logger log;

	    @SidedProxy
	    (clientSide =  "ru.Morttal.RPGcore.proxies.ClientProxy", serverSide = " ru.Morttal.RPGcore.proxies.CommonProxy")
	    public static CommonProxy proxy;
	    
	    @EventHandler
	    public void preInit(FMLPreInitializationEvent event)
	    {
	        proxy.preInit(event);
	    }

	    @EventHandler
	    public void init(FMLInitializationEvent event)
	    {
	        proxy.init(event);
	    }

	    @EventHandler
	    public void postInit(FMLPostInitializationEvent event)
	    {
	        proxy.postInit(event);
	    }
}

RPGMainEvent : 

package ru.Morttal.RPGcore.gui;

import net.minecraft.client.gui.GuiMainMenu;
import net.minecraftforge.client.event.GuiOpenEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class RPGMainEvent {
	 @SubscribeEvent
	    public void openCustomGuiMainMenu(GuiOpenEvent e)
	    {
	        if (e.getGui()  instanceof GuiMainMenu)
	            e.setGui(new RPGMainMenu());
	           
	    }
}

RPGMainMenu :

package ru.Morttal.RPGcore.gui;

import net.minecraft.client.gui.GuiMainMenu;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.resources.I18n;



public class RPGMainMenu extends GuiMainMenu {
	public String old = "";
	
	public RPGMainMenu() {
		super();
	}
	public void addSingleplayerMultiplayerButtons(int p_73969_1_, int p_73969_2_)
	{
		this.buttonList.clear();
		this.buttonList.add(new GuiButton(1, this.width / 2 - 100, p_73969_1_, I18n.format("menu.singleplayer")));

	}
}

Also, have line MinecraftForge.EVENT_BUS.register(new RPGMainEvent()); in client proxy and in the main class, but nothing works. No errors, but the buttons are not missing!
