Yes. This is happening to me all the time and it's making all of my gameplays in the sims a disaster. It's like Biff from the movie "Back To The Future" is controlling the autonomy of all sims turning them into savages. This occurs just by simply being in gameplay and controlling the household. It's already bad that sims get angry very often from unfulfilled dreams. Anger from unfulfilled dreams alone causes me to have my sims calm down in front of a mirror far more than I should. Now we have sims randomly, unconditionally lashing out insults and mean interactions at each other. The worst part is that sims hold grudges now which can be triggered by a single insult. When a sim holds a grudge against another sim, they are immediately put in a negative mood just by being around that sim. My weakness is, I don't just create households and families. I create worlds. I've created nearly 200 sims and around 100 of them are able to come visit any household I happen to be controlling. With this insult crisis bug going on between all of the sims, it severely detracts from all of the accomplishments I had in making all of those sims and having them be as wonderful and respectful as I want them all to be.
I understand that the Sims is a game that mimics life. We all know that life is hard. Some players would actually find it amazing that the sims mimics life for what it is, while other players would see it as a harsh reminder. I love the game and I really hope for a fix to happen and to see that my sims get along again. Maybe Rodney King should make an appearance in the sims.
