Stage 1 glitch- local sided ----- No output error?

Hello, I really don't have much information on this issue other than the fact that sometimes when players load in, on their screen it saying they are on stage one, while on everyone else's screen it's the stage the player is actually on.

My script for saving stages

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

game.Players.PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("IntValue")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local level = Instance.new("IntValue")
	level.Name = "Stage"
	level.Parent = leaderstats
	level.Value = 1
	
	local key = "user-" .. player.userId
	
	local storeditems = datastore:GetAsync(key)
	if storeditems then
		level.Value = storeditems[1]
	else
		local items = {level.Value}
		datastore:SetAsync(key, items)
	end
	local spawn = game.Workspace:WaitForChild(player.leaderstats.Stage.Value)
	if player and spawn then
		player.Character:MoveTo(spawn.Position + Vector3.new(0, 3, 0))
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local items = {player.leaderstats.Stage.Value}
	local key = "user-" .. player.userId
	datastore:SetAsync(key, items)
end)

game.Workspace.ChildAdded:connect(function(obj)
	local player = game.Players:GetPlayerFromCharacter(obj)
	if player then
		local leaderstats = player:FindFirstChild("leaderstats")
		local stage = leaderstats:FindFirstChild("Stage")
		local respawn = game.Workspace:WaitForChild(stage.Value)
		obj.Torso.CFrame = obj.Torso.CFrame + Vector3.new(0,3,0)
		wait(0.1)
		obj.Torso.CFrame = respawn.CFrame + Vector3.new(0,3,0)
	end
end)
