Chat script broken?

So recently I’m pretty sure Roblox updated the Player.Chatted function to make it where doing
Player.Chatted:Connect(function(Message) is useless.
Like I mean after doing that function ^^^ the “Message” bit of it is useless but I’ve figured a way to fix it now it’s fine but it’s also broken one of my admin commands.

My admin commands work like this string.sub(Message,1,5) == "blah blah blah" and then once you do that it gets the player by doing local oPlr = game.Players:FindFirstChild(string.sub(Message, 7)) so then I make it kill them or something after that and it used to work but now it doesn’t does anyone know why?? Is it deprecated?
