Studio sometimes fails to load leaderstats

Help and Feedback Scripting Support

I’m not sure why this is happening but studio sometimes fails to load leaderstats:

Script:

local DataStoreService = game:GetService("DataStoreService")
local DataStoreModule = require(1936396537) -- Datastore 2
local BadgeService = game:GetService("BadgeService")

-- Define the data keys and their default values
local dataKeys = {
	-- leaderstats
	{name = "Coins", defaultValue = 0, dataType = "IntValue", parent = "leaderstats"},
	{name = "Wins", defaultValue = 0, dataType = "IntValue", parent = "leaderstats"},
	-- Settings
	{name = "Music", defaultValue = true, dataType = "BoolValue", parent = "data"},
	-- data
	{name = "InRound", defaultValue = false, dataType = "BoolValue", parent = "data"},
}

-- Combine the keys in DataStoreModule
local keys = {}
for _, data in ipairs(dataKeys) do
	table.insert(keys, data.name)
end
DataStoreModule.Combine("MasterKey", unpack(keys))

-- Helper function to create value instances for leaderstats or data folder
local function createValueInstance(data, parent)
	local valueInstance = Instance.new(data.dataType)
	valueInstance.Name = data.name:gsub("^%l", string.upper)
	valueInstance.Parent = parent
	valueInstance.Value = data.defaultValue -- Set default value initially
	return valueInstance
end

-- Function to load player data and connect it for live saving
local function loadDataAndConnect(data, player, valueInstance)
	local dataStore = DataStoreModule(data.name, player)
	local success, storedValue = pcall(function()
		return dataStore:Get()
	end)

	-- Set the value to either the stored value or the default if unavailable
	if success then
		valueInstance.Value = storedValue ~= nil and storedValue or data.defaultValue
	else
		warn("Failed to load data for", data.name, "for player", player.Name)
	end

	-- Save updated values on change with retry handling
	valueInstance:GetPropertyChangedSignal("Value"):Connect(function()
		local retries = 3
		while retries > 0 do
			local success, errorMsg = pcall(function()
				dataStore:Set(valueInstance.Value)
			end)
			if success then break end
			retries -= 1
			if retries == 0 then
				warn("Failed to save data for", data.name, "for player", player.Name, ":", errorMsg)
			else
				wait(2) -- Wait before retrying to handle throttling
			end
		end
	end)
end

-- Player added function to initialize leaderstats and data folders
game.Players.PlayerAdded:Connect(function(player)
	local leaderstatsFolder = Instance.new("Folder", player)
	leaderstatsFolder.Name = "leaderstats"

	local dataFolder = Instance.new("Folder", player)
	dataFolder.Name = "data"

	for _, data in ipairs(dataKeys) do
		local parentFolder = data.parent == "leaderstats" and leaderstatsFolder or dataFolder
		local valueInstance = createValueInstance(data, parentFolder)
		loadDataAndConnect(data, player, valueInstance)
	end
end)

-- Save data when player leaves
game.Players.PlayerRemoving:Connect(function(player)
	for _, data in ipairs(dataKeys) do
		local dataStore = DataStoreModule(data.name, player)
		local valueInstance = player:FindFirstChild(data.parent):FindFirstChild(data.name)
		if valueInstance then
			local retries = 3
			while retries > 0 do
				local success, errorMsg = pcall(function()
					dataStore:Set(valueInstance.Value)
				end)
				if success then break end
				retries -= 1
				if retries == 0 then
					warn("Failed to save data for", data.name, "for player", player.Name, "on removal:", errorMsg)
				else
					wait(2)
				end
			end
		end
	end
end)

PlayerAdded is known for not always firing inside studio due to the Script reaching that point after the Player Instance is created.
