Are you trying to setup a single table inheritance type thing? When you say that your universities data disappears, do you mean that University.all no longer returns any data? Switching from your previous setup to a single table inheritance situation means that mongomapper will be looking in the topics collection when you do University.all, so I'm not surprised that your university data would appear to vanish, if you haven't done anything to move it from its previous collection.
