Tween messes up positioning

[Happypigbaconalt]

so im trying to make a cat that can walk to different windows, however after the first window it goes to, its positioning gets all messed up.

--SERVICES--
local ServerStorage = game:GetService("ServerStorage")
local TweenService = game:GetService("TweenService")

local TInfo = TweenInfo.new(10)
local SInfo = TweenInfo.new(3)

--OBJECTS--
local Windows = workspace.Windows:GetChildren()
local Debounce = false
local Maxwell = ServerStorage.maxwell
local Humanoid = Maxwell.Humanoid

--ANIMS--
local ShakeAnim = Instance.new("Animation")
ShakeAnim.AnimationId =	Maxwell.Shake.AnimationId
local ShakeAnimTrack = Humanoid:LoadAnimation(ShakeAnim)


while task.wait(math.random(1, 10)) do
	if Debounce == false then
		Debounce = true
		
		ShakeAnimTrack:Stop()
		
		local random = Windows[math.random(1, #Windows)]
		random.Window.Material = Enum.Material.Neon
		
		Maxwell.HumanoidRootPart.Position = random.Spawn.Position	
		Maxwell.Parent = workspace
		Maxwell.maxwell.Size = Vector3.new(5.096, 3.005, 2.579)
	
		print(Maxwell.HumanoidRootPart.Position)
		print(random.Spawn.Position)
		
		random.Window.ProximityPrompt.Enabled = true
		
		task.wait()
		
		

		local Tween = TweenService:Create(Maxwell.HumanoidRootPart, TInfo, {Position = random.Window.Position}) 
		Tween:Play()
		
		Maxwell.Weld.Position = Maxwell.HumanoidRootPart.Position
		
		Tween.Completed:Connect(function()
			random.Window.ProximityPrompt.Enabled = false
			Tween:Destroy()
			ShakeAnimTrack:Play()
			
			local SizeTween = TweenService:Create(Maxwell.maxwell, SInfo, {Size = Vector3.new(9, 6, 5)})
			SizeTween:Play()
			ShakeAnimTrack.Stopped:Connect(function()
				SizeTween:Destroy()
				Maxwell.Parent = ServerStorage
				Debounce = false
			end)
		end)
		
		
		delay(1, function()
			random.Window.Material = Enum.Material.SmoothPlastic
		end)
	elseif Debounce == true then
	end
end
