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)
