Not sure what issue you’re facing here, but it’s definitely a backdoor within your game, I’d install a plugin called [Venom] (https://www.roblox.com/library/4216304328/Venom-Intercept-Malicious-Scripts) which was made by a Roblox Employee part of their work, it’ll scan and dissect all scripts, and plugins to find anything malicious.
Furthermore, Roblox will be publishing a new change soon, which should theoretically completely blow Backdoors out of the water.
Yes, I’ve seen this too, and the game has Kohl’s admin infinite (backing your claim :D).
I’ve seen this, too and I think if you just delete the red flag parts of the script, you should be left with a fully functional admin.
that custom loadstring implementation, is the way that kohls admin allows administrators in the game to run the script command, yes, they have a command for running scripts on the server, they use the custom loadstring module to avoid getting users to enable loadstring.
