NPC moves smooth but begins to stutter after a while, what's the matter?

So the NPC moves smoothly to the destination once or twice but then starts to pause at each waypoint for an unknown reason, or, at least unknown to me... I asked this in the Discord server a few times, but nothing I tried from there works. What can I do to fix it?

while true do
	local post = campPosts[math.random(1, #campPosts)]
	path:ComputeAsync(torso.Position, post.Position)
	local waypoints = path:GetWaypoints()
	for i, v in pairs(waypoints) do
		if v.Action == Enum.PathWaypointAction.Jump then
			humanoid.Jump = true
		end
		humanoid:MoveTo(v.Position, post)
		humanoid.MoveToFinished:Wait()
		path.Blocked:Connect(function()
			path:ComputeAsync(torso.Position, post.Position)
		end)
	end
	print("lastHere")
	if post.Name == "optionalPost" then
		wait(5)
	elseif post.Name == "importantPost" then
		wait(30)
	elseif post.Name == "mandatoryPost" then
		break
	end
end
