NPC appears not not follow the player when being cloned In repicatedstorage?

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)
