Why wont the datastore work? It use to work but all of the sudden it wont?

local Data = game:GetService("DataStoreService"):GetDataStore("ThrowsDataSaver")

game.Players.PlayerAdded:Connect(function(plr)
	local folder = Instance.new("Folder", plr)
	folder.Name = "leaderstats"
	
	local Throws = Instance.new("IntValue", folder)
	Throws.Name = "Throws"
	Throws.Value = 0
	
	local dataLoad = Data:GetAsync(tostring(plr.UserId))
	
	if dataLoad then
		Throws.Value = dataLoad[1]
	end
end)
game.Players.PlayerRemoving:Connect(function(plr)
	Data:SetAsync(tostring(plr.UserId),{
		plr.leaderstats.Throws.Value
	})
end)

Its most likely because you havent defined a game:BindToClose when the last player leaves the server shutdowns and which can cause data to not save, bc the playerremoving event may not execute on time (its unreliable)

see this article on how to properly save
