Bake Lightmaps from batchmode corrupted LightingDataAsset

Hi,

I'm having an issue when baking lightmaps from a static function invoked via command line arguments using Unity batchmode.

Unity version: 2017.4.5f1, 2017.3.1p1

Code (CSharp):

1.  public static void BakeLightMap()
2.     {
3.         var config = GetCommandLineArgsDictionary(Environment.GetCommandLineArgs());
4.         var scenes = config.GetArray<string>("sceneList", ',');
5.         foreach (var scene in scenes)
6.         {
7.             EditorSceneManager.OpenScene(scene);
8.             Lightmapping.ClearLightingDataAsset();
9.             Lightmapping.Bake();
10.             //EditorSceneManager.MarkAllScenesDirty();
11.             EditorSceneManager.SaveOpenScenes();
12.         }
13.  
14.         AssetDatabase.SaveAssets();
15.     }

LightningDataAsset has been build but it seems to be corrupted and obviously the scene is not lit:


I have also tried invoking Unity through Windows Task Scheduler (which opens a new window).
Surprisingly for a set of scenes the last one was properly lit (and LightningDataAsset was not corrupted).

So I'm thinking I'm doing something wrong with saving scene or assets rather then the batchmode itself.
