The issue here does not seem to be what everyone is addressing. If I understood Anh correctly, when you run update_attribute X on a unsaved model that has one attribute Y set in memory, calling reload will report both X and Y as saved, so it seems to be a reload issue at first glance. I will try and reproduce it shortly.
