Pathfinding script all of the sudden doesn't work

Help and Feedback Scripting Support
#1

I made a pathfinding script for an NPC. I followed the Pathfinding tutorial and made sure to follow every step precisely. When I finished it, it worked perfectly fine, it did everything I wanted it to. Then I hopped off Studio for the night.

When I went back on this morning and launched the NPC, it all of the sudden won’t bother going around obstacles and walks straight to the target. I didn’t tamper with the script or NPC at all, I just closed my laptop for the night. I’ve tried digging through the script and output looking for errors, but none were there.

I am very sorry if I overlooked an obvious thing, but I just didn’t see anything. Help would be greatly appreciated. Here is the script:

local PathfindingService = game:GetService("PathfindingService")

local motivator = game.Workspace.motivator
local humanoid = motivator.Humanoid
local destination = game.Workspace.GreenFlag

local path = PathfindingService:CreatePath()

path:ComputeAsync(motivator.HumanoidRootPart.Position, 
destination.PrimaryPart.Position)

local waypoints = path:GetWaypoints()

for _, waypoint in pairs(waypoints) do
    local part = Instance.new("Part", game.Workspace)
    part.Shape = "Ball"
    part.Material = "Neon"
    part.Size = Vector3.new(.6,.6,.6)
    part.Position = waypoint.Position
    part.Anchored = true
    part.CanCollide = false

    humanoid:MoveTo(waypoint.Position)
    humanoid.MoveToFinished:Wait()
end
