1) Revive Events: with the events rush and the missing units (some skipped events and the loli-units) a reviving could be really useful for old and new players, during the weekends would be perfect.

2) Loli units: i can "understand" the lack of them but they are useful, like... REALLY, useful. A work around could be to disable their H-scenes until times come or using their All-ages scenes.

3) New story missions: i guess it's pretty much time...?

About shutting down the game to "fix the problems", that's an horrible solution in my opinion
