Why doesn't my data save to the datastore on leave or server shutdown?

I have another script that saves every 2 minutes, so I know that the save script does work. It just doesn't save when someone leaves or the game closes.

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local DS = game:GetService("DataStoreService"):GetDataStore("Data")

function save(player)
    local data = DS:GetAsync(player.UserId)
    data["tokens"] = player:FindFirstChild("Tok").Value
    data["combatLogged"] = player:FindFirstChild("CombatLogged").Value
    DS:SetAsync(player.UserId, data)
    print("Data Saved!")
end

Players.PlayerRemoving:Connect(function(player)
    wait(3)
    save(player)
    print("Saved "..player.Name.."'s data!")
end)

game:BindToClose(function()
    wait(1)
    for i, player in ipairs(Players:GetPlayers()) do
        coroutine.wrap(save)(player)
        print("Saved "..player.Name.."'s data!")
    end
end)
