Not sure if it's an unstable bug, but

めっっっちゃ分かります。さっきまでのやり取りを全部無かったことにされた感、特に苦労して敵倒して排除したのに速攻復活されるとめっちゃしんどい。あと、味方キャラでも、別の部屋に居たはずなのに玄関から尋ねて来る、とか…ユーザーの目の前に居ないと消失した扱いになるのか瞬間リポップしてくるの場の雰囲気と空気読めてなさすぎてエグい。

The free version of AI can basically only remember about 10 tokens. If that topic never comes up, contradictions in its memory might appear earlier, causing the AI to arbitrarily adjust the narrative and change the plot. As a workaround, you can enter the following into your talk profile: "Event Log: [Character Name] was executed for the crime of [Cause]." This will prevent them from appearing in the future. The more detail you add, the less likely the AI is to create plot inconsistencies to fill in the gaps, so try to make good use of your talk profile.

Even if you execute the villainess or exile her to an island... she keeps coming back like a doll you throw away (›´ω`‹ )
