Tome of Town Portal 2 serialization failure

[collinsmith]

One item during my testing has an issue with serialization due in part to the fact that it was modified by a save file editor. The item is a Tome of Town Portal with the socketed flag set on it, which when serialized by my item serializer removes the flag, while the original client preserves it. I do not anticipate this being an issue, but I'd like to look into gracefully handling this error at some point, as it exists on one of my save files and throws an error.
