Thanks for letting me know.
That is ... unfortunate, but I supposed it's easy enough to manage, since the new table only needs to store the start/end dates and allowed time for each quiz. It just adds a level of complexity to the plugin that I wanted to avoid.
I also tried changing the "internal" value from true to false, when declaring the observer, since that does let you perform tasks before the database changes happen on creating a new quiz. I don't really understand why that doesn't work for updates.
