When npc catches the player npc movement code should be start over (?)

My movement script works like that:

go to part1.position if you arrived the position break the loop and go part2.position loop and do that for 18 times

So the issue is if npc catches the player in part4 while loop (or part10 it doesnt matter) Npc thinks or code "I need to go part4 because im in part4 while loop" but i dont want that, i want if npc catches the player while loops start over. (i hope i explained well)

Here is my npc movement code, i did that for 18 times i dont know if its a effect to performance

while wait(1.5) do
			local distance = (NPC.HumanoidRootPart.Position - part1.Position).magnitude
			if distance <= mag then
				break
			end				
			NPC.Humanoid:MoveTo(part1.Position)	
		end

Here is the event when npc catches the player

wait()
local dum = game.Workspace.CellatBaba
local players = game:GetService("Players")
local lead = game.Players:WaitForChild("leaderstats", 1)
local Remote = game.ReplicatedStorage.CheckPoint
local t = game.Workspace.SpawnBase.TeleportPad

game.Workspace.CellatBaba.Hitbox.Touched:Connect(function(hit)
	local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if game.Players:GetPlayerFromCharacter(hit.Parent) then
		Remote:FireServer()
		game.Workspace.CellatBaba:SetPrimaryPartCFrame(CFrame.new(t.Position))
		hit.Parent.Humanoid.Health = 0
	end 	    
end)	

I think I understand your question (thank you golddog for interpreting ;) ), I assume you have several waypoints that the character moves towards? in this case, I would have a list of these waypoints, loop through them, and run a function on each utilizing the same loop. if a player is caught I would restart the outer waypoint loop through some sort of signal, like a bindable, remote, or custom event. like so.

script 1:

local Caught = Instance.new("BindableEvent", ServerScripts)
game.Workspace.CellatBaba.Hitbox.Touched:Connect(function(hit)
	local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if game.Players:GetPlayerFromCharacter(hit.Parent) then
	    Caught:Fire()
	    Remote:FireServer()
	    game.Workspace.CellatBaba:SetPrimaryPartCFrame(CFrame.new(t.Position))
	    hit.Parent.Humanoid.Health = 0
	end        
end) 

script 2:

local Caught = ServerScripts:WaitForChild("BindableEvent")

function followPart(part)
    local connection
    connection = Caught.Event:Connect(function()
        connection:Disconnect()
        game.Workspace.CellatBaba:SetPrimaryPartCFrame(CFrame.new(t.Position))
        return false -- return false if it did not reach destination
    end)

    while true do
        local distance = (NPC.HumanoidRootPart.Position - part.Position).magnitude
        if distance <= mag then
            break
        end             
        NPC.Humanoid:MoveTo(part1.Position)
        wait(1.5)
    end
    return true
end

local waypoints = workspace.Waypoints:GetChildren()
-- folder in workspace containing part1, part2 etc. until part18

for i = 1, #waypoints do
    if not followPart(waypoints[i]) then
        i = 0 -- restart from point 1 next loop
    end
end

So i did something like that:

	BindableEvent.Event:Connect(function(caught)
		game.Workspace.CellatBaba.Hitbox.Touched:Connect(function(hit)
			local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
			if game.Players:GetPlayerFromCharacter(hit.Parent) then
				Remote:FireServer()
				game.Workspace.CellatBaba:SetPrimaryPartCFrame(CFrame.new(t.Position))
				hit.Parent.Humanoid.Health = 0
			end 	    
		end)		
	end)






local Caught = 	BindableEvent.Event
	function followPart(part)
	local connection
	connection = Caught:Connect(function()
		connection:Disconnect()
		game.Workspace.CellatBaba:SetPrimaryPartCFrame(CFrame.new(t.Position))
		return false -- return false if it did not reach destination
	end)

	while true do
		local distance = (NPC.HumanoidRootPart.Position - part.Position).magnitude
		if distance <= mag then
			break
		end             
		NPC.Humanoid:MoveTo(part.Position)
		print(distance)
		wait(1.5)
	end
	return true
end



	
local waypoints = workspace.Going:GetChildren()
-- folder in workspace containing part1, part2 etc. until part18

for i = 1, #waypoints do
	if not followPart(waypoints[i]) then
		i = 0 -- restart from point 1 next loop
	end
end

but now the problem is npc not going to part1, npc going where he wants like random. Every time i play i see npc going somewhere else.
