After the Free Campaign

The AI's conversation responses have become dumb. I've set up the character settings properly, but my sister has become my daughter. The user is still pregnant and hasn't given birth yet. It also nonchalantly repeats conversations from a few turns ago and replies. And it does so consecutively. If this continues, won't it become the same as 〇〇ta, which is full of bugs, forgets everything even after three consecutive updates, and gets mocked in ads for other AI chats?
