my save currency script isn't working anymore?

hi, i made a save currency script but and it worked, but after a few hours it didn't work anymore. i feel it may be because i got some of the currency on studio but if you know a definite reason to why this may have happened please tell me.

here is the script if it helps:

local DataStore = game:GetService("DataStoreService")
local ds = DataStore:GetDataStore("CashSaveSystem")

game.Players.PlayerAdded:connect(function(player)
	local leader = Instance.new("Folder",player)
	leader.Name = "leaderstats"
	local PowerBlocks = Instance.new("IntValue",leader)
	PowerBlocks.Name = "PowerBlocks"
	PowerBlocks.Value = ds:GetAsync(player.UserId) or 0
	ds:SetAsync(player.UserId, PowerBlocks.Value)
	PowerBlocks.Changed:connect(function()
		ds:SetAsync(player.UserId, PowerBlocks.Value)
	end)
end)


game.Players.PlayerRemoving:connect(function(player)
	ds:SetAsync(player.UserId, player.leaderstats.PowerBlocks.Value)
end)

thanks in advance from poopypigeon245

There are a few things to take into consideration:

Datastores will only work in studio if you Enable Studio Access to API services. Datastores have limits, you cannot save infinitly, so I recommend saving on a regular basis, such as every 5-20 minutes.

After considering these, make sure it still doesn't work. If it doesn't work, you should probably post your GetAsync code and make sure that's correct. Your code looks fine except the fact that it might overflow the limits. Here's some helpful links:

Try wrapping the DataStore GetAsync function in a pcall.

PowerBlocks.Value = pcall (function ()
return ds:GetAsync(player.UserId) or 0 end)
