There are so many sims now that behave mischievously even though they don't have a single negative trait!!! I hate this so much because I know every interaction can't be perfect but it's so annoying ...
Ideas
I have tried blocking the mischief with MCCC - both by specific interactions as well as broad "disable mischief" category. Despite blocking specific interactions by name, the next time I start the game they'll do the behavior that had already been blocked.
I'm setting up an unmodded save now as well and will send that save file.
