So I wanted to add a GUI to a block and I copied from another one of my mods but however, I crash with this every time I go and right click on the block: http://pastebin.com/x5SvFfHy

 

Code (Open source Yay! ): Problem Line

@Override
    public Object getClientGuiElement(int id, EntityPlayer player, World world, int x, int y, int z){
        TileEntity te = world.getTileEntity(x, y, z);
        if(te instanceof TileEntityBlockCrafter){
            return new ContainerBlockCrafter(player.inventory, (TileEntityBlockCrafter) te);
        }
        return null;
    }

 

You are returning your Container on the client, return your Gui class not the Container
