title: Why is meteor adding ObjectId around the _id field since today?
body: <p>Maybe I'm completely wrong, but since projects that I start today, when I use meteor mongo to connect directly to the mongodb, and insert a record (with mycol.insert(..) the _id field is surrounded with ObjectId("12345555...").
  When adding a record from code this is not the case.
  So, records added via Meteor Mongo are not recognised inside the app any longer.
  I have done this in the past so often...
  what's happening here?</p>
