I'm having this too. I got tired of random sims coming for a scare on my lot so I removed the lot trait.
Now I get the specific ghostly bored moodlet sometimes when I load into the game. The sim wasn't even doing anything. Also when I move them to another lot the moodlet just comes up. while the new lot never had the trait or any other.
I've repaired the game and refreshed the sims 4 documents file. Still there.
Experiencing the exact same thing. I removed the lot challenge and my Sims are still getting the related bored moodlet for not getting scared. It does however, only seem to be happen to the household I used it on. Moving lots, travelling, playing other households does not remove the issue. Other households seem to be unaffected so long as I never activate the lot challenge. I am wondering if the event items are somehow accidentally tied to the lot trait? I'll have to test it out by removing them all from the lot
