NPC acting like its dumb

I wan’t to get the NPC to not be glitchy.
Heres a clip of the npc

local TweenService = game:GetService("TweenService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local npc = script.Parent.Dummy -- The NPC model
local humanoidRootPart = npc:FindFirstChild("HumanoidRootPart")
local humanoid = npc:FindFirstChildOfClass("Humanoid")
local walk = ReplicatedStorage.GameMechanics.Animations.WalkAnimation
local idle = ReplicatedStorage.GameMechanics.Animations.IdleAnimation
if not humanoidRootPart or not humanoid then
	warn("HumanoidRootPart or Humanoid missing from NPC!")
	return
end

-- Define movement points
local points = {
	script.Parent:WaitForChild("Point1").Position,
	script.Parent:WaitForChild("Point2").Position,
	script.Parent:WaitForChild("Point3").Position
}

-- Load animations
local animator = humanoid:FindFirstChildOfClass("Animator")

local walkAnimation = walk:Clone()

local idleAnimation = idle:Clone()

local walkTrack = animator:LoadAnimation(walkAnimation)
local idleTrack = animator:LoadAnimation(idleAnimation)

local tweenInfo = TweenInfo.new(3, Enum.EasingStyle.Linear, Enum.EasingDirection.Out)

local function moveToPoint(index)
	if walkTrack then walkTrack:Play() end -- Start walking animation

	local goal = {Position = points[index]}
	local tween = TweenService:Create(humanoidRootPart, tweenInfo, goal)
	tween:Play()
	tween.Completed:Wait() -- Wait until movement completes

	if walkTrack then walkTrack:Stop() end -- Stop walking animation
end

while true do
	moveToPoint(1) -- Move to Point 1
	task.wait(1) -- Short pause

	moveToPoint(2) -- Move to Point 2
	if idleTrack then idleTrack:Play() end -- Play idle animation while waiting
	local waitTime = math.random(10, 60) -- Random wait time
	task.wait(waitTime)
	if idleTrack then idleTrack:Stop() end -- Stop idle animation

	moveToPoint(3) -- Move to Point 3
	task.wait(1) -- Short pause
end

the black cubes are the points it moves to.

donot use tweens to move npc that has a humanoid , instead use Humanoid:MoveTo(Position , Part) pass the position of the way point in the first argument and the way point itself in the second argument and to track when the humanoid reachs the waypoint use Humanoid.MoveToFinish:Wait()
