How to fix a script that disappears when joining the game?

HI! Could someone help me out? I am developing a game since a few days and i have a data saving script in ServerScriptService. The problem is, everytime i join my game the script disappears :/ This is the script: local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(player) local CurrentOrb = game.ReplicatedStorage.CurrentOrb

local data
local success, errormessage = pcall(function()
	data = myDataStore:GetAsync(player.UserId.."-CurrentOrb")
end)

if success then
	CurrentOrb.Value = data
else
	print("There was an error whilst getting your data, sorry :(")
	warn(errormessage)
end

end)

game.Players.PlayerRemoving:Connect(function(player)

local success, errormessage = pcall(function()
	myDataStore:SetAsync(player.UserId.."-CurrentOrb",game.ReplicatedStorage.CurrentOrb.Value)
end)

if success then
	print("Player Data saved")
else
	print("There was an error when saving data")
	warn(errormessage)
end

end)
