Hello! So Its been a long time since I've talked about Pathfinding, so anyway, I decided to edit with the pathfinding I did and I found a random problem, basically for some whatever reason, the script would randomly stop working, meaning the NPC won't chase the player(s). However sometimes It does work, however It will randomly break and once It breaks It literally becomes Impossible for the NPC to chase the player(s) as Its pathfinding script just randomly broke

Note: The edit that I did was that I removed the NPC.Humanoid.MoveToFinish code so that way It can go chase players without having to go to the original player spot (For example, If the player moves lets say, 20 studs while the npc Is chasing them, the npc must need to go to there original spot so they can change locations)

Script:

local NPC = script.Parent
local PathfindingService = game:GetService('PathfindingService')
local Players = game:GetService("Players")
local player

game.Players.PlayerAdded:Connect(function(client)
	player = client
end)

repeat wait() until player ~= nil

local path = PathfindingService:CreatePath()

while wait() do
	local path = PathfindingService:CreatePath()
	
	path:ComputeAsync(NPC.Torso.Position, player.Character.PrimaryPart.Position)

	if path.Status == Enum.PathStatus.Success then
		local Positions = path:GetWaypoints()

		for i,v in pairs(Positions) do
			local ball = Instance.new("Part", workspace)

			ball.Position = v.Position
			ball.Anchored = true
			ball.CanCollide = false
			ball.Size = Vector3.new(4,4,4)
			ball.Transparency = 0
			ball.Shape = Enum.PartType.Ball

			NPC.Humanoid:MoveTo(ball.Position)
		end
	end
end
