Comment by @HilariousCow:

I've found that if the ScriptableObject class you have created has references to other ScriptableObjects, then the time at which you use JsonUtility.FromJsonOverwrite is important.
If the objects references have not been loaded into the scene yet, then during deserialisation, the ID of that object will not be in the unity lookup table, and thus that field will come back as "default(T)" (i.e. "null")
If you are loading save game data, my advice is to use the JsonUtility.FromJsonOverwrite AFTER the content for your game is loaded.
Or use something else (I've heard Odin is good).
