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()

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.

Credits

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 ;)
