Why is Humanoid:MoveTo functioning strangely?

I've been trying to figure out why this happens, but I just can't for the life of me figure it out. Local script:

local cam = workspace.CurrentCamera
local hum = workspace.FINSKMANN.Humanoid
local debounce = false

local function Chat(msg)
	game.Chat:Chat(workspace.FINSKMANN.Head, msg, Enum.ChatColor.White)
end

game.ContextActionService:BindAction('Start', function()
	game.Players.LocalPlayer.PlayerGui.ScreenGui:ClearAllChildren()
	
	if not debounce then
		debounce = true
		cam.CameraType = 'Scriptable'
		
		game:GetService('RunService').RenderStepped:Connect(function()
			cam.CFrame = CFrame.new(workspace.CamPos.Position, workspace.CamRot.Position)
		end)
		
		wait(2)
		
		Chat("Maybe it wasn't the best idea to go camping ALONE, especially here in the Cosaqiezsa forest...")
		hum:MoveTo(Vector3.new(-4.5, 0, 8.5))
		local prevTick = tick()
		hum.MoveToFinished:Wait()
		print(tick() - prevTick)
		
		wait(2.25)
		
		Chat('Whatever.. Surely it can not get that bad.')
	end
end, false, 'g')

If I provide no input after I press G, 8 prints out (because the :MoveTo function times out after 8 seconds if humanoid has not yet reached provided Vector3). If I walk behind FINSKMANN (the character), then FINSKMANN moves.

I'm no ROBLOX physics expert, so any help is appreciated.

First, I don't know if it will work or not. But, I am sure that it might be the problem of NetworkOwnership. And, if the 'FINSKMANN' is a NPC, it might be the problem. To fix it, add this line before :MoveTo():

-- Make sure you have it inside ContextActionService, and before :MoveTo() part

local rootPart = workspace.FINSKMANN.PrimaryPart
rootPart:SetNetworkOwner(nil) -- nil is 'Server'

Lemme know if it helps!
