Error on manually deserializing ScriptableObject

I'm working on a networked turn based game. I've created data structures that mirror the data stored on the server. I've set up serialization / deserialization so that I can encrypt the data and store it locally to the hard disk, so that is persists between play sessions (loads on start up, saves on application close). I've set up serialization / deserialization from JSON objects so that it can sync the data coming from the server.

All these classes extend from a common base class, which has some error handling built in to automatically report errors that may occur.

Now, I'm trying to convert the data classes to extend ScriptableObject. I don't really need Unity to serialize and save the data on its own, I just want it to be able to pass some of the data around in PlayMaker (which requires that it extend UnityEngine.Object). I also tried setting the hide flags in OnEnable to make it so that unity wouldn't save the data on its own, but I'm still getting the same error.

I modified the base class to extend ScriptableObject, cleared the local data file, ran it to generate fresh data, and closed it save the data.

Then when I run it again, and it tries to deserialize the saved data, it results in this error:

Any ideas on what is breaking this? It worked fine before I started extending ScriptableObject (and works fine if I remove it and reset the data)
