Humanoid:MoveTo movements are not working right?

Hello, I am making 15-20 NPCs walk randomly between points. But, after a few seconds, the movements get less smooth and jittery.

Code

for i, point in pairs(waypoints) do
		script.Parent:MoveTo(point.Position + Vector3.new(0,3,0))
		local move = false
		script.Parent.MoveToFinished:Connect(function()
			move = true
		end)
		script.Parent.MoveToFinished:Wait()
	end

Any help is appreciated thanks

I found a workaround. If you set the waypoint distance to a higher number, and you use a line of code to wait just before the NPC gets to the destination, some stuttering happens but it is very minimal.
