A heirarchy of user classes (Rpg, Character, Combat, Enemy, etc.). I did figure out a way to get around this - I added jsonpickle to site-packages, and then I'm storing the encoded object in a json field in the table.
But yes, that was the error I got with the binary version of the pickle, stored in a blob field. With the text version, I got an "unrecognized token" error, which seemed to be happening because the field wasn't being escaped correctly.
