I am no longer receiving death notifications for my sim's friends. I do get the notification that would usually follow the notice, "being sorry for your loss etc.", but that doesn't tell you which sim passed away. This is problematic when playing an aspiration like Friend of the World where there are twenty friends in the friend list. I have no way of knowing if it is a sim I might want to host a funeral for.
It's further complicated by the issue reported here Dead sims are not greyed out in the relationship panel/Family tree | EA Forums - 4952469 It's certainly hard to tell who passed away when they are suddenly looking very much alive again. I did also post my experience and a screenshot with that issue in the referenced thread.
I can't say with certainty when this issue started. I have only noticed it since installing the 8/19/25 patch. I play on PC and have never used mods or cc. I didn't associate this with a pack tag because it should affect all of them, so I wasn't sure what to do.
