Datastores Across Universe?

I've been working on my project, and it uses DataStores across a universe.

Here is script one

local datastore = game:GetService("DataStoreService"):GetDataStore("Vestige")

game.Players.PlayerRemoving:connect(function(leavingplayer)
	wait(2)
	local stats = leavingplayer:FindFirstChild("Statistics"):GetChildren()
	for x = 1,#stats do
		print(stats[x].Name)
	end
end)

game.Players.PlayerAdded:connect(function(player)
	wait(2)
	local newstats = player:FindFirstChild("Statistics"):GetChildren()
	for x = 1, #newstats do
		newstats[x].Value = datastore:GetAsync(newstats[x].Name)
	end
end)

Here is the script in the other place in the universe

local datastore = game:GetService("DataStoreService"):GetDataStore("Vestige")

script.Parent.MouseClick:connect(function(plr) 
	if plr.PlayerGui:findFirstChild("ScreenGui") then
		print("already clicked")
	else
		local cl = script.Parent.ScreenGui:Clone()
		cl.Parent = plr.PlayerGui
		game.Players.PlayerRemoving:connect(function(leavingplayer)
			leavingplayer.Statistics.Coins = leavingplayer.Statistics.Coins + 10
			wait(2)
			local stats = leavingplayer:FindFirstChild("Statistics"):GetChildren()
			for x = 1,#stats do
				print(stats[x].Name)
			end
		end)
	end
end)

The GUI part of the second script works, but it doesn't add any more coins. Could anyone help?

Try removing the wait(2)s. Its possible that due to the player leaving, the player leaves before the data can be saved.
