I'll start with I play on PC and I don't use any mods. I started a new character for the event, a single female living in Willow Creek. I was able to do the event through the planting of the flowers ...
Ideas
Same on my end. Never had any mods installed, new game character. Newsletter disappeared from my inventory after I tried reading it.
Issue still happening, tried the following so far and no luck:
- Move household to another home/map;
- Starting a new game;
- Tried all available mailboxes;
- Reinstalled the game 3x;
- Repaired the game once.
