Date store not reading async commands?

I have been trying to learn data store from many articles and tutorials. I always follow along, remember to switch on HTTP services for studio, and write everything exactly as they tell me to. Though when they get a saved result, I don't. I've tried putting print statements in my code, and I've found that it skips the Get and Set Async lines. Any help would be greatly appriciated.

DataService = game:GetService("DataStoreService")
DataStore = DataService:GetDataStore("DataStore1")

game.Players.PlayerAdded:Connect(function(player)
	print("player joined")
	local leaderstats = Instance.new("Folder", player)
	leaderstats.Name = "leaderstats"
	print("leaderstats made")
	local Credits = Instance.new("IntValue", leaderstats)
	Credits.Name = "Credits"
	print("credits made")
	
	local PlayerId = "id_"..player.UserId
	print("id achieved")
	
	--// Loading data
	
	local data 
	print("made data variable")
	local success, errormessage = pcall(function()
		print("entered first pcall")
		
			data = DataStore:GetAsync(PlayerId)
			print("gotten data")
		
	end)
	
	if success then
		Credits.Value = data
	else 
		print("something went wrong when loading")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	print("player left")
	local PlayerId = "id_"..player.UserId
	print("loaded id")
	
	--// Saving data
	
	local success, errormessage = pcall(function()
		print("entering pcall")
		wait()
		DataStore:SetAsync(PlayerId, player.leaderstats.Credits.Value)
		print("saved")
		
	end)
	
	if success then
		print("data saved wohoo")
	else
		print("data not saved oh no")
		warn(errormessage)
	end
	
end)

Found out that the studio server closed too early for the script to run properly, and once it went out into a public server worked just fine.
