Detecting players and game working wrong?

I am trying to make it so when 2 players are in the game, maps will be chosen out of the ServerStorage and cloned into Workspace and the players will go there. But when I test it, ServerStorage is empty, which causes it to not work. Why does it become empty? I also tried putting the maps in ReplicatedStorage and it didn't work, though they didn't remove. It is in a LocalScript, which was in ReplicatedFirst. I tried putting the code into a normal script inside workspace, it just displayed the gui. I tried using a game.Players.PlayerAddedfunction. It just displayed the gui. Nothing else. Sorry about the long question :/

maps = game.ServerStorage:GetChildren()
local player = game:GetService"Players".LocalPlayer
local guis = player:WaitForChild"PlayerGui"


while wait(.5) do
    if game.Players.NumPlayers >= 2 then
        guis.ScreenGui.Frame.Map.Visible = false
        guis.ScreenGui.Frame.Madeby.Visible = false
        wait(3)
        ranmap = math.random(1, #maps)
        guis.ScreenGui.Frame.Visible = true
        guis.ScreenGui.Frame.Beingchosen.Visible = true
        wait(1)
        chosen = maps[ranmap]
        chosenclone = chosen:Clone()
        chosenclone.Parent = game.Workspace
        guis.ScreenGui.Frame.Map.Visible = true
        guis.ScreenGui.Frame.Madeby.Visible = true
        guis.ScreenGui.Frame.Madeby.Text = "Map is " .. chosen.Name .. " By: Spoookd"
        wait(5)     
        spawn = chosenclone.SpawnPoint
        for i,v in pairs(game.Players:GetPlayers()) do
            name = v.Name
            check = game.Workspace:FindFirstChild(name)
            if check then
                checkHumanoid = check:FindFirstChild("Humanoid")
                if checkHumanoid then
                    check:MoveTo(spawn.Position)
                end
            end
            guis.ScreenGui.Frame.Visible = false
        end
    else
        guis.ScreenGui.Frame.Visible = false--I moved this
        h = Instance.new("Hint", game.Workspace)
        h.Text = "You need more than 1 player to play."
    end
end
