why dosen't my script work in "Starting Server.." mode?

I am currently testing for my minigame, but for some reason the minigames dosen't work in "Starting server.." mode, is there something I am missing? Because the script work perfectly fine in "Play" mode.

wait()

minigames = game.ReplicatedStorage.Minigames:GetChildren()
numPlayers = game.Players.NumPlayers

while wait() do

    if numPlayers >= 1 then

    print("Starting")

    randGame = math.random(1, #minigames)

    print(randGame) 

    chosenGame = minigames[randGame]
    print(chosenGame)

    -------------------------------------------------------
    if randGame == 1 then

        cloneGame = game.ReplicatedStorage.Minigames.Dissapearing_Grass:Clone()
        cloneGame.Parent = game.Workspace
        wait(5)
        cloneGame:Destroy()
        wait(3)
    end
    ------------------------------------------------------- 

    -------------------------------------------------------
    if randGame == 2 then

        cloneGame = game.ReplicatedStorage.Minigames.Dissapearing_Grass2:Clone()
        cloneGame.Parent = game.Workspace
        wait(5)
        cloneGame:Destroy()
        wait(3)
    end
    ------------------------------------------------------- 
    -------------------------------------------------------     
    if randGame == 3 then

        cloneGame = game.ReplicatedStorage.Minigames.Dissapearing_Grass3:Clone()
        cloneGame.Parent = game.Workspace
        wait(5)
        cloneGame:Destroy()
        wait(3)
    end
    -------------------------------------------------------

    -------------------------------------------------------     
    if randGame == 4 then

        cloneGame = game.ReplicatedStorage.Minigames.Dissapearing_Grass4:Clone()
        cloneGame.Parent = game.Workspace
        wait(5)
        cloneGame:Destroy()
        wait(3)
    end
    -------------------------------------------------------

    -------------------------------------------------------     
    if randGame == 5 then

        cloneGame = game.ReplicatedStorage.Minigames.Dissapearing_Grass5:Clone()
        cloneGame.Parent = game.Workspace
        wait(5)
        cloneGame:Destroy()
        wait(3)
    end
    -------------------------------------------------------

    end
