I agree it's silly to not have the events from other packs loaded in. I only bought Seasons because I wanted the calendar to show me when the City Living and Get Together events were going on ahead of time so my Sim could take time off. I am extremely disappointed to find that not only are these events not automatically listed in the calendar, but that there's no way to add them in ourselves without adding some clunky holiday mechanic that overlaps the event. Keeping track of events you're (at least interested in) attending is quite literally the entire point of keeping a calendar that shows you events well ahead of time!
If you can't/won't have the game automatically add the various pack events as players buy/add packs, then please consider adding a simple "note" field to the calendar so we can add the events (or other random reminders, like karaoke contest nights, happy hour times, etc.) in for ourselves. Thanks!
