So this Is a little problem so I made a script that makes the NPC find the player and follows the player:

local function FindTarget()
	local maxDistance = 10000
	local target = nil
	for i,v in pairs(workspace:GetChildren()) do
		if v:FindFirstChild("Humanoid") then
			if (v.Head.Position-script.Parent.Head.Position).magnitude < maxDistance then
				target = v.Head
			end
		end
	end
	return target
end

while wait() do
	local target = FindTarget()
	if target then
		script.Parent.Humanoid:MoveTo(target.Position)
	end
end

And I made a test part spawner that spawns the NPC (Which Is named Noob btw)

local part = script.Parent
local rep = game.ReplicatedStorage

wait(1)
local NPC = rep.Noob:Clone()
NPC.Parent = game.Workspace
NPC.Position = script.Parent.Position
NPC.Orientation = script.Parent.Orientation

This sadly however makes the NPC not follow the player just Instead stands there, also I founded out that It targets NPCS that are clones from replicatedstorage (I think)

(ALSO the following script does work)
