Subject: [PATCH] Update Functional.cs

Replace .ToArray() with .ToList() to allow dynamic modification of network_nodes

Replaced .ToArray() with .ToList() to resolve the issue where .Add() was called on a fixed-size array. Lists allow dynamic modification, preventing the "Collection was of a fixed size" error.
