For the latest update, I have no content for some of the events:
Easter - Happened on a Friday. On entering the hallway for the first time the scene to go to church triggered. There are decorations in the house but no events trigger. Visiting different rooms in the house also do not trigger anything.
Josef's birthday - It was a Tuesday so the bath audio played when entering the hallway, but no event triggered. There are balloons in the hallway and I can visit him in his office and wish him, but there is no other scene.
Anniversary - nothing - no decorations, no special scene triggers.
Adrian's birthday - It was a Monday so on entering the hallway the normal scene of Charolette talking Adrian triggered, but no event triggers. There are balloons in the hallway. but there is no other scene.
I had no issue with christmas and the new years scenes.
