Pathfinding rig slows down over time

Anyone know why the rig slows down over time when its wandering? After its been running for about 2 minutes it stops longer and longer in between each waypoint

I tried seeing if the issue was network ownership but it wasn’t
Anyone know what causes this issue?

function module:Wander()
	wandering = true
	pathfinding = false
	following = false
	
	if pathfindThread then
		task.cancel(pathfindThread)
	end
	
	pathfindThread = task.spawn(function()
		while not pathfinding and wandering do
		local AllPaths = #path:GetChildren()
		local randomPoint:Part = path:GetChildren()[math.random(1, AllPaths)]
		repeat randomPoint = path:GetChildren()[math.random(1, AllPaths)] until randomPoint ~= lastPoint
		lastPoint = randomPoint
		humanoid:MoveTo(rig:GetPivot().Position)
		local path = pathfindingService:CreatePath(agentParameters)
		path:ComputeAsync(rig:WaitForChild("HumanoidRootPart").Position, randomPoint.Position)
		local waypoints = path:GetWaypoints()
			if path.Status == Enum.PathStatus.NoPath then
				warn("Invalid pathfind: ".. rig.Name.. " move to "..tostring(randomPoint.Position).. " -Wander")
			end
		
		if showPathfind then
			rig.Waypoints:ClearAllChildren()
			for _, waypoint in ipairs(waypoints) do
				local part = Instance.new("Part")
				part.CanTouch = false
				part.CanCollide = false
				part.CanQuery = false
				part.Anchored = true
				part.Size = Vector3.one
				part.Position = waypoint.Position
				game.Debris:AddItem(part, 10)

				part.Parent = rig.Waypoints
				part.Name = "Path"
			end
		end

			local totalWaypoints = #waypoints
			local currentWaypoint = 0
			for _, waypoint in ipairs(waypoints) do
				if wandering and not following and not pathfinding then
					humanoid:MoveTo(waypoint.Position)
					currentWaypoint += 1
					humanoid.MoveToFinished:Wait()
				end
			end

			--print(currentWaypoint.. "/"..totalWaypoints)
			if currentWaypoint == totalWaypoints and path.Status == Enum.PathStatus.Success then
				print(rig.Name.." Reached path: "..tostring(randomPoint.Position).. " -Wander")
				
				task.wait(4)
			end
		end
		
		
	end)
end
