Not sure if it is a bug or feature, but if one of your puppeted cities gets captured, then you retake the city it becomes a standard liberated city under your control. This meets the Venice guidelines of not Annexing or Settling a city.
Not hugely imbalanaced or anything because in order to take advantage of it you need to have your city decimated by 2 captures, but still something to keep in mind.
