Scriptable Object not serializing

Can anyone help figure out why my scriptable object asset won't serialize? It generates the data fine but when I reopen Unity the values are all reset.

It's probably something stupid and I'm too sleepy to see it.

Here's the editor script that creates the scriptable object asset, pretty sure this all correct.

Code (csharp):

1.  
2. public class FontDataExtractor
3. {
4.     [MenuItem ("Custom/Extract Font Data")]
5.     public static void ExtractFontData()
6.     {
7.         var font = Selection.activeObject as Font;
8.  
9.         if (font == null)
10.         {
11.             EditorUtility.DisplayDialog("No Font Selected","Select font from project tree","OK");
12.             return;
13.         }
14.        
15.         SerializedObject info = new SerializedObject(font);    
16.         FontData fontData = null;
17.            
18.         string path = "Assets/FontData/" + font.name + "Data" + ".asset";      
19.         object asset = AssetDatabase.LoadAssetAtPath(path, typeof(FontData));
20.        
21.         if(asset == null)
22.         {
23.             fontData = ScriptableObject.CreateInstance<FontData>();
24.            
25.             string assetPathAndName = AssetDatabase.GenerateUniqueAssetPath(path);
26.             AssetDatabase.CreateAsset(fontData, assetPathAndName);
27.         }
28.         else
29.         {
30.             fontData = asset as FontData;
31.         }
32.  
33.  
34.         fontData.kerning = info.FindProperty("m_Kerning").floatValue;
35.         fontData.lineSpacing = info.FindProperty("m_LineSpacing").floatValue;
36.         fontData.convertCase = info.FindProperty("m_ConvertCase").intValue;
37.  
38.         int size = info.FindProperty("m_CharacterRects.Array.size").intValue;
39.        
40.         fontData.glyphs = new FontData.Glyph[size];
41.        
42.         for (int i = 0; i < size; i++)
43.         {
44.             var glyph = new FontData.Glyph();
45.            
46.             glyph.index = info.FindProperty("m_CharacterRects.Array.data["+i+"].index").intValue;
47.             glyph.uvs = info.FindProperty("m_CharacterRects.Array.data["+i+"].uv").rectValue;
48.             glyph.verts = info.FindProperty("m_CharacterRects.Array.data["+i+"].vert").rectValue;
49.             glyph.spacing = info.FindProperty("m_CharacterRects.Array.data["+i+"].width").floatValue;
50.            
51.             fontData.glyphs[i] = glyph;
52.         }
53.        
54.  
55.         AssetDatabase.SaveAssets();
56.         EditorUtility.FocusProjectWindow();
57.         Selection.activeObject = fontData;
58.     }
59. }
60.  

Here's the scriptable object code...

Code (csharp):

1.  
2. public class FontData : ScriptableObject
3. {
4.     public float kerning;
5.     public float lineSpacing;
6.     public int convertCase;
7.     public Glyph[] glyphs;
8.    
9.    
10.     [System.Serializable]
11.     public class Glyph
12.     {
13.         public Rect verts;
14.         public Rect uvs;
15.         public float spacing;
16.     }
17. }
18.  

 

Yep, that did the trick. Knew it would be something simple. Thanks Superpig.
