Resolved Can't add to a List?

I'm trying to make an offline scoreboard for my game. Here's the current code:

Code (CSharp):

1. public void addScoreEntry(int score, string name) {
2.         ScoreEntry newEntry = new ScoreEntry(score, name);
3.         Debug.Log("New entry: " + newEntry.score + " " + newEntry.name);
4.  
5.         scoreEntryList.Add(newEntry);
6.  
7.         string json = JsonUtility.ToJson(scoreEntryList);
8.         PlayerPrefs.SetString("highscoreTable", json);
9.         PlayerPrefs.Save();
10.         Debug.Log(PlayerPrefs.GetString("highscoreTable"));
11.     }

The sorting hadn't been implemented yet. At first I tried to Insert the entry at the right position, but that didn't work either.
Anyway, the problem is that when the last Debug.Log is called, the List still seems to be empty, as if the Add never happened. Anyone who can help with this?
It can't be that the list isn't initialized, because I have this in the Awake() of the same component:

Code (CSharp):

1. if (PlayerPrefs.HasKey("highscoreTable")) {
2.             scoreEntryList = JsonUtility.FromJson<List<ScoreEntry>>(PlayerPrefs.GetString("highscoreTable"));
3.         }
4.         else {
5.             scoreEntryList = new List<ScoreEntry>();
6.         }

 

Stay away from Unity's JSON. It cannot do dictionaries or hashsets and looks from here it cannot do lists either. Not only that but it fails with properties and I can't even remember what else. Just do not use.

Go to the asset store and get JSON .NET... it's FREE! It's a "Real" JSON, not a "Tiny" JSON

 

This tutorial seems to do it just fine with the built-in JSON, but I'll try the asset.
