Autonomous Insults are Back

My one of my two married sims has started insulting their spouse autonomously. She has no traits that would cause this and the relationship has positive relationship dynamics and sentiments. This only started happening after she got pregnant (game hasn't registered it yet) and after the most recent update. I have played for several hours on this save file and this is the first pregnancy I have had on it. She is now autonomously arguing with her partner and insulting him. Also, I cannot take a pregnancy test. I have removed all MODS and CC, also repaired the game.
