I JUST restarted before I saw this thread! And it's not my first restart either (and won't be my last). I even made a thread a few years back asking if I should feel bad for doing so lol.
I usually restart when I've been away from my game for awhile and I forget what I had planned for my sims. Other times it's when something right goes COMPLETELY wrong and I can't fix it. This time around, some townies died but I didn't know how long ago nor how many. I was just playing my main household then I got a notification, "Katrina's spirit is fading". I'm sorry, WHAT?! KATRINA'S DEAD?! Then I found out Mortimer is gone too! The remaining Goth's moved to the city but I couldn't find them in any of the households! And I have lost many other sims that I was completely unaware of. I was unaware of the neighborhood stories until AFTER all of this and much more had happened!
