My Inventory is not saving to DataStore?

Here is my server script in workspace:

local ds = game:GetService("DataStoreService")
local played = ds:GetDataStore("PLAY3D")
local invs = ds:GetDataStore("Inventory")
local function load(plr)
	local f = Instance.new("Folder",game.ServerStorage)
	f.Name = tostring(plr.Name)
    local playedbefore = Instance.new("BoolValue",plr)
	playedbefore.Name = "PlayedBefore"
	playedbefore.Value = played:GetAsync(plr.UserId,playedbefore.Value) or false
	wait()
	if playedbefore.Value == true then
		local inv = {}
		for i = 500000,0,-1 do
			local s, e = pcall(function()
				invs:GetAsync(plr.UserId,inv)
			end)
			if e then
				warn(e)
			else
				print("Loaded Data!")
				break
			end
		end
		wait()
		local num = table.getn(inv)
		if num >= 1 then
			for i, v in pairs(inv) do
				local cl = game.ReplicatedStorage:WaitForChild(v):Clone()
				local cll = game.ReplicatedStorage:WaitForChild(v):Clone()
				cl.Parent = plr.Backpack
				cll.Parent = plr.StarterGear
			end
		end
	else
		local inv = {"Sword"}
		wait()
		local num = table.getn(inv)
		if num == 1 then
			for i, v in pairs(inv) do
				local cl = game.ReplicatedStorage:WaitForChild(v):Clone()
				local cll = game.ReplicatedStorage:WaitForChild(v):Clone()
				cl.Parent = plr.Backpack
				cll.Parent = plr.StarterGear
			end
		end
	end
end

local function save(plr)
    local inv = {}
	for i, v in pairs(game.ServerStorage:WaitForChild(plr.Name)) do
		table.insert(inv,#inv,v.Value)
		v:Destroy()
	end
	wait()
	for i = 50000,0,-1 do
		local s, e = pcall(function()
			invs:SetAsync(plr.UserId,inv)
		end)
		if e then
			warn(e)
		else
			break
		end
	end
	if plr:WaitForChild("PlayedBefore").Value == false then
		for i = 50000,0,-1 do
			local s, e = pcall(function()
				played:SetAsync(plr.UserId,true)
			end)
			if e then
				warn(e)
			else
				break
			end
		end
	end
end

game:GetService("Players").PlayerAdded:Connect(function(plr)
   load(plr)
end)

game:GetService("Players").PlayerRemoving:Connect(function(plr)
    save(plr)
end)
game:BindToClose(function()
    for _, client in ipairs(game.Players:GetPlayers()) do
		coroutine.wrap(save)(client)
		wait(100)
    end
end)

Here is my server script in StarterPlayerScripts:

repeat warn("Parent is not a player."); wait() until script.Parent:IsA("Player")
local plr = script.Parent
local area = plr:WaitForChild("StarterGear")
if #area:GetChildren() > 0 then
	for i, v in pairs(area:GetChildren()) do
		local f = game.ServerStorage:WaitForChild(plr.Name)
		local ins = Instance.new("StringValue",f)
		ins.Name = "Item"
		ins.Value = v.Name
	end
end
area.ChildAdded:Connect(function(obj)
	local f = game.ServerStorage:WaitForChild(plr.Name)
	local ins = Instance.new("StringValue",f)
	ins.Name = "Item"
	ins.Value = obj.Name
end)

Could someone help me out here?
