How to teleport all players into the map?

Hi! So I have been following a AlvinBlox Tutorial

I have wrote down everything he did but only one player get teleported to the map.

The code below this is the Main Script

-- Define Variables

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ServerStorage = game:GetService("ServerStorage")

local MapsFolder = ServerStorage:WaitForChild("Maps")

local Status = ReplicatedStorage:WaitForChild("Status")

local GameLength = 50

local reward = 25

-- Game Loop

while true do

    Status.Value = "Waiting for enough players"

    repeat wait(1) until game.Players.NumPlayers >= 2

    Status.Value = "Intermission"

    wait(10)

    local plrs = {}

    for i, player in pairs(game.Players:GetPlayers()) do
        if player then
            table.insert(plrs,player) -- Add each player into plrs table
        end
    end

    wait(2)

    local AvailableMaps = MapsFolder:GetChildren()

    local ChosenMap = AvailableMaps[math.random(1,#AvailableMaps)]

    Status.Value = ChosenMap.name.." Chosen"

    local ClonedMap = ChosenMap:Clone()
    ClonedMap.Parent = workspace

    -- Teleport Players to the map

    local SpawnPoints = ClonedMap:FindFirstChild("SpawnPoints")

    if not SpawnPoints then
        print("SpawnPoints not found!")
    end

    local AvailableSpawnPoints = SpawnPoints:GetChildren()

    for i, player in pairs(plrs) do
        if player then
            character = player.Character

            if character then
                --Teleport them

                character:FindFirstChild("HumanoidRootPart").CFrame = AvailableSpawnPoints[1].CFrame
                table.remove(AvailableSpawnPoints,1)

                -- Give them a sword

                local Sword = ServerStorage.Sword.Clone()
                Sword.Parent = player.Backpack

                local GameTag = Instance.new("BoolValue")
                GameTag.Name = "GameTag"
                GameTag.Parent = player.Character

            else 
                --There is no character
                if not player then
                    table.remove(plrs,i)
                end
            end
        end
    end

    Status.Value = "Get ready to play!"

    wait(2)
    for i = GameLength,0,-1 do

        for x, player in pairs(plrs) do
            if player then

                character = player.Character

                if not character then
                    -- Left the game
                else
                    if character:FindFirstChild("GameTag") then
                        -- Still alive 
                        print(player.Name.." is still in the game!")
                    else 
                        -- They are dead
                        table.remove(plrs.x)
                    end

                end
            else
                table.remove(plrs,x)
                print(player.Name.." has been removed")
            end
        end

        Status.Value = "There are "..i.." seconds remaining, and "..#plrs.." players left"

        if #plrs == 1 then
            --Last person standing
            Status.Value = "The WINNER is "..plrs[1].Name
            plrs[1].leaderstats.Bucks.Value = plrs[1].leaderstats.Bucks + reward
            break
        elseif #plrs == 0 then
            Status.Value = "Nobody won!"
            break
        elseif i == 0 then
            Status.Value = "Nobody Won!"
        end

        wait(1)
    end

    print("End of game")

    for i, player in pairs(game.Players:GetPlayers()) do
        character = player.Character

        if not character then
            -- Ignore them
        else 
            if character:FindFirstChild("GameTag") then
                character.GameTag:Destroy()
            end

            if player.Backpack:FindFirstChild("Sword")then
                player.Backpack:Destroy()
            end

            if character:FindFirstChild("Sword")then
                character.Sword:Destroy()
            end
        end

        player:LoadCharacter()

    end

    ClonedMap:Destroy()

    Status.Value = "Game Ended"

    wait(2)

end

There are no errors in the code. (Nothing in the output or the script analyser) Please help me. Thanks to all of you in advance.
