From a local instance, with the lastest commit (a238997), with a fresh crossbar started up right before shark:

Are you seeing anything like this?

btw, I wrote a script to make it easy to query meta.last_event on an identifier

I'm just now starting to write tests for Serializable, which should reveal any issues that are happening here.

If nothing comes out of that, then it is probably a configuration issue, though I can't see anything wrong with the current (a238997) configuration.

1) Shark::Serializable with a default configuration includes all attributes
     Failure/Error: expect(serialized).to include(:name, :list, :hash)

       expected {:identifier => "dummyclasss.Main", :associated_objects => {Shark::DummyClass => ["dummyclasss.Main.1", "dummyclasss.Main.2"]}} to include :name, :list, and :hash
       Diff:

       +:associated_objects => {Shark::DummyClass=>["dummyclasss.Main.1", "dummyclasss.Main.2"]},

There is indeed an error. I'm really not sure how this happened, since it was working before, and I don't remember much of anything changing. Regardless, I'll get on fixing this shortly.
