Nested Dictionary Change Value Problem

Hi Unity Community, thank you for looking at my post. I will get str8 to the point. I have having an issue with changing, the values in a nested Dictionary, There are no errors and most of it works as expected but it does not respect a particular key and changes the value for all entries.

I have set up a test that replicates my problem, if you run this class and then hit "A" you will see a debug output of the dictionary as I set it up (all as expected). Then you hit "B" and it will change the values of the dictionary in a very specific way. BUT ONLY for a specific day!, then you hit "C" and what you will find is that it changed the value for every day, ignoring the key for the day.

Here is the class. Sorry to include your name @aldonaletto but this seams right up your ally. Any idea?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class TestScript : MonoBehaviour
 {
 
     //The Master Dictionary to hold <location < day index < hour index < price>>>> 
     Dictionary <string,Dictionary<int,List<int>>> priceByHour;
 
     //The defualt price, value to change. 
     private int defaultPrice = 3;
 
     void Start ()
     {
         // Initilazing master Dictionary
         priceByHour = new Dictionary<string, Dictionary<int, List<int>>> ();
 
         // The locations
         List<string> locations = new List<string> {"NY"};//, "LA", "Chenarous", "Azaroth", "York", "Lancaster"};
         foreach (string loc in locations) {
 
             //Create Hours List with the prices
             List<int> hours = new List<int> ();
             for (int i = 0; i < 24; i ++) {
                 hours.Add (defaultPrice);
             }
 
             // Create Days list with the hours and prices
             Dictionary<int,List<int>> days = new Dictionary<int, List<int>> ();
             for (int i = 0; i < 7; i ++) {
                 days.Add (i, hours);
             }
 
             // add it all to the master dictionary.
             priceByHour.Add (loc, days);
         }
     }
 
 
     // To Test and review;
     void Update(){
         //Print out the content of the master dictionary
         if (Input.GetKeyDown (KeyCode.A)) {
             PrintOutMasterDictionary();
         }
 
         // change the values
         if (Input.GetKeyDown (KeyCode.B)) {
             ChangeValuesOfDayTwo();
         }
 
         // print againg to compare result
         if (Input.GetKey (KeyCode.C)) {
             PrintOutMasterDictionary();
         }
         // Notice that the dayToChange was set to index 4 but it changed the value of every over after the 6th hour to the new price! 
     }
 
 
     // Print out the result to compare after the change.
     void PrintOutMasterDictionary ()
     {
         foreach (KeyValuePair<string,Dictionary<int,List<int>>> masterEntry in priceByHour) {
             Debug.Log ("Location = " + masterEntry.Key);
             foreach (KeyValuePair<int,List<int>> day in masterEntry.Value) {
                 Debug.Log ("Day = " + day.Key.ToString ());
                 for (int i = 0; i < day.Value.Count; i ++) {
                     Debug.Log ("Hour = " + i.ToString () + " has a value of " + day.Value [i].ToString ());
                 }
             }
         }
     }
 
     void ChangeValuesOfDayTwo(){
 
         // set change perameters
         int dayToChange = 4;
         int newPrice = 5;
         string locationToChange = "NY";
         int hourToChangeBehind = 6;
 
         //Iterate through all possible hours
         for (int i = 0; i < 24; i++) {
             // if the hour is greater than hour to change, change the value
             if(i > hourToChangeBehind){
                 priceByHour[locationToChange][dayToChange][i] = newPrice;
             }
         }
     }
 }
 

Thank you.
