Hi All,
I've made some changes to the code. I have improved the modifier code. It should be more robust now and not mess up on calls to the base class. I have also implemented a custom serialization binder which can cope with missing items when a character is loaded. If it can't load the type, a missing item token should appear in your inventory. If the type is avaliable when you next log on, it will be restored from the missing item token.
I have also implemented some code that enforces a few programming rules. You will notice this one because none of your assemblies compile now! You need to implement ISerializable in any classes that derive from Thing or Effect.
Happy serializing!
