Need Help with a Duplication Issue

So, I released my server a couple weeks ago and we gave out guns to the gangs and they are managing to duplicate them, I found out the method that they are using to duplicate. The method is making a FiveM shortcut and putting -cl2 at the end then they load in the server with two fivem’s and drop the gun and then leave on the shortcut FiveM and then pick it up on their main FiveM and now they have two guns.

Is there any way to fix this if so, can anyone lead me in the right direction it would be appreciated as it’s ruining my server.

… bad post

Thank you for the help, I’ll test it out.

  1. The sv_lan option is off by default.
  2. This has nothing to do with ‘preventing players from running multiple instances’, there’s no built-in functionality for this, this is something a resource should do in the playerConnecting handler.
  3. sv_lan = 0? Nothing in the server config file uses =. Are you sure you’re not a bot (or posting GPT-generated replies?)

I dont know what framework are you are using, QBCore has a check for duplicate license.

you can implement something like this on your server
