Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
This might be currently an unnoticed bug (not caused by the Crystal Creations patch but others suggest it occurred since the infant update) since most players don't use mischief interactions quite often or others think it always ends up negative by default. I played a mischievous sim a while ago and I knew mischief interactions could end positively, especially following their mischief level, charisma level, traits, likes and dislikes, and relationships.
To be fully sure of this bug, I created a fresh UNMODDED save (download link attached) with 2 sims in a household, both having the Goofball trait, both liking mischief, both having high mischief and charisma levels (since I've read charisma determines social interaction success rate), both having the maximum friendship level with each other, and both feeling playful. Even with all that, all mischief interactions fail. All mischief interaction under Deception fails, some Pranks rarely work, specifically the "Trick with Hand Buzzer" interaction but still end up reducing friendship.
