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 ...

I came upon this report because I'm also having issues with mischief. My sims are also doing mischief frequently, but what bothers me is that all mischief interactions fail making sims dislike them and affecting their relationships negatively. Which is also discussed in this report/thread:

Although this report is not about the frequency, I still think it might be relevant here. As said before, mischief interactions aren't supposed to (always) be negative. Sims should mostly enjoy pranks (they used to before this bug). But with this bug, mischief interactions are always failing (regardless of traits, skill level and likes/dislikes) which makes sims not like them and make it seem that these are negative interactions. And when you experience your sims are constantly doing mischief it becomes really annoying.
