I don't know if it is whether a bug or a feature, but I noticed when the schedule's day changes, mine is set to 3am, renshuu also interrupts at least the shiritori cat game and the Japanese Lessons' videos.
It is a bit annoying, so I wonder if it could be avoided.
It does force a reset of the page, yes. It would get messier than not to try and work around that, so I recommend the reset time to be right in the middle of your sleep :)
