Don't forget about the missing training scenes and the inventions testing parts for Hatsume :P
I was getting 'WORK IN PROGRESS' announcement from training scenes in the Gym (non-sexual kind) and from the Inventions (if I remember correctly) bit with Hatsume interactions, though Hatsume also seemed to crash somewhere on the way there and all sorts of progression with her ceased completely (none of the interactions options did anything, and that was following a rollback page).
