Bool Value not being detected

Help and Feedback Scripting Support
#1

Below is the code in a local script to check if an npc has a bool value (named Finished) set to false. Each NPC has a unique name. It works perfectly for a while then I get the error “Finished is not a valid member of Model Workspace.NPCsInWorld.Rig(R15)78”

local function GetNPCWhiteList()
	local Whitelist = {}
	
	for i, Model in pairs(game.Workspace.NpcsInWorld:GetChildren()) do
		if Model.Finished.Value == false then
			for i,modelpart in pairs(Model:GetDescendants()) do
				if modelpart:IsA("BasePart") or modelpart:IsA("Part") then
					Whitelist[#Whitelist+1] = modelpart
				end
			end
			
		end
	end
	return Whitelist
end

I understand that this error means the bool value doesn’t exist on the client, but I don’t know why. This is how the NPCs are created on the Server:

local namenum = 0
NPCModule.CreateNPC = function(player)
	local profile = PlayerDataCache[player]
	if profile then
		
		local Model
		local num = math.random(1,#game.ReplicatedStorage.NPCS.Defaults:GetChildren())
		for i,v in ipairs(game.ReplicatedStorage.NPCS.Defaults:GetChildren()) do
			if i == num then
				Model = v:Clone()
			end
		end
		
		for i,v in pairs(Model:GetDescendants()) do
			if v:IsA("Part") or v:IsA("BasePart") or v:IsA("MeshPart") then
				PhysicsService:SetPartCollisionGroup(v,"NPCs")
			end
		end
		Model:WaitForChild("Finished")
		print("Finished waiting")
		
		namenum += 1
		Model.Name = Model.Name..namenum
		Model.Parent = game.Workspace.NpcsInWorld
	
		
		local humanoid = Model:WaitForChild("Humanoid")
		PlayAnimationForHumanoid:FireAllClients(humanoid)
		humanoid.WalkSpeed = math.random(6,9)
		
		
	end
end

I removed the irrelevant bits. As you can see, the bool value exists in the models I clone, and I even go out of the way to wait for it. Idk why the client eventually fails to find it.
