Effect from Scare Seeker lot challenge doesn't go away after removing it/moving

Your Sim has this hidden moodlet

You should be able to remove it with MCCC. Could you check if that makes a difference 

Also this trait: 

I think this got left behind when you turned off the lot. Maybe it even works to just remove the trait. and the buff will run out on it's own.

Could you also upload the LE you're getting ? Either upload as rar (I hope that works here) or c/p the content.
