@dragancaor finally someone else is having the same problem. It would be an annoying bug if you are particular on the relationship health between sims.
I'm pretty sure it's from the social bunny app when they receive a negative message in their dms, it affects the relationship with that sim through social bunny, positive and negative comments and reactions affect relationships.
You can deactivate social bunny when you open it up and it should stop that, but it it also won't help you build relationships faster if you deactivate.
There is a huge discussion about this topic here: https://answers.ea.com/t5/Bug-Reports/OPEN-Autonomous-Insulting-Patch-1-92-145/td-p/11932091
This seems to have started right after the last update. We believe it has something to do with the new loyalty trait. I heard from somewhere in these forums EA has confirmed it is a bug and is looking into it.
