I've noticed it, too. Atm I prompt every message. Check your writing instructions (helps a little bit) and maybe emphasize chars being (very) friendly and never aggressive (in char description and prompts, but tbh, I didn't try that myself yet bc I'm at a point in my story where I have an important argument with my char.)

Edit: If necessary, go completely over-the-top with the description, we had to do that to create negative traits with the old model, maybe it's now the other way.
