My sim has been living in Nordhaven since it was released, but since she's moved in she seems to keep receiving death notices about mere acquaintances, on an almost in game weekly basis. Due to this, she is pretty much always in a state of grieving at some level or another.
I'm honestly not sure if this is an actual bug, or if the game is just being rather death happy with this particular sim of mine. (I remember people posting about a similar issue when L&D was released, but I never experienced it with my Ophelia sim, that I have living in Ravenwood.) 😥
