Thanks to KASH and XxFri3ndlyxX

Required changes:

• es_extended: (es_extended/client/main.lua)

Replace AddEventHandler('playerSpawned', function() (35) with:

RegisterNetEvent('esx:kashloaded')
AddEventHandler('esx:kashloaded', function()

• es_extended: (es_extended/server/main.lua)

Change this code in onPlayerJoined(playerId) function:

	for k,v in ipairs(GetPlayerIdentifiers(playerId)) do
		if string.match(v, 'license:') then
			identifier = string.sub(v, 9)
			break
		end
	end

to:

	for k,v in ipairs(GetPlayerIdentifiers(playerId)) do
		if string.match(v, 'license:') then
			identifier = v
			break
		end
	end

WARNING!

You MUST incerase characters limit in users table for row identifier to 48.

Pay ATTENTION: You have to call the resource 'esx_kashacters' in order for the javascript to work!!!*

How it works

What this script does it manipulates ESX for loading characters So when you are choosing your character it changes your Rockstar license which is normally license: to Char: this prevents ESX from loading another character because it is looking for you exact license. So when you choose your character it will change it from Char: to your normal Rockstar license (license:). When creating a new character it will spawn you without an exact license which creates a new database entry for your license.

ESX Framework and KASH AND Onno204 for creating the resource. You can do whatever the f with it what you want but it is nice to give the main man credits ;)
