"Waiting System" is not working? (Explain Problem)

I am attempting to make a system that waits til all the players are in the game.

They is one server script that listens and see if a player joins. When a player joins it checks if they are a "Hunter" or "Survivor" through a data store. If they are a "Hunter" then it fires to the client to update GUI and put them on the Hunter side of the GUI. If they are a "Survivor" then it fires to the client to update GUI and put them on the Survivor side of the GUI.

Server Script:

local Event = game.ReplicatedStorage.Events:WaitForChild("LobbyEvent")
local Players = game:GetService('Players')
local hunter = nil

game.Players.PlayerAdded:Connect(function(plr)
    print(plr.Name.." Has Joined")
    for i, v in pairs(game.Players:GetChildren()) do
        print("Checking through players 1st")
        for _, a in pairs(game.Players:GetChildren()) do
            print("Checking through players 2nd")
            if game.ServerStorage[plr.Name]:WaitForChild("Current").Value == "Hunter" then
                Event:FireClient(v, a.Name, "Hunter")
                print("It's A Hunter")
            elseif game.ServerStorage[plr.Name]:WaitForChild("Current").Value == "Survivor" then
                Event:FireClient(v, a.Name, "Survivor")
                print("It's A Survivor")
            end
        end
    end
end)

Client Script:

local HCard = game.ReplicatedStorage:WaitForChild("HunterCard")
local SCard = game.ReplicatedStorage:WaitForChild("PlayerCard")
local plr = game.Players.LocalPlayer
local Event = game.ReplicatedStorage.Events:WaitForChild("LobbyEvent")

Event.OnClientEvent:Connect(function(plr, Name, Position)
if Position == "Survivor" then
    if not script.Parent.Lobby.Main.LobbyFrame.Survivorlane:FindFirstChild(plr) then
        local SCardClone = SCard:Clone()
        SCardClone.Parent = script.Parent.Lobby.Main.LobbyFrame.Survivorlane
        SCardClone:FindFirstChild("Name").Text = Name
        SCardClone:FindFirstChild("Image").Image = "http://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&username="
        SCardClone.Name = Name
    end
elseif Position == "Hunter" then
    if not script.Parent.Lobby.Main.LobbyFrame.Hunterlane:FindFirstChild(plr) then
        local HCardClone = HCard:Clone()
        HCardClone.Parent = script.Parent.Lobby.Main.LobbyFrame.Hunterlane
        HCardClone:FindFirstChild("Name").Text = Name
        HCardClone:FindFirstChild("Image").Image = "http://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&username="
        HCardClone.Name = Name
        end
    end
end)
