fireflyの「お気に入り」のサンプル画像が開けない

そのような挙動に遭遇したことがないのでブラウザに保存されている情報がおかしくなっているなどが考えられそうです。ブラウザのローカルストレージ等を削除するかブラウザを別のものに変えて試すとどうでしょう？

Hello @ろぺ84_2 ,

Thank you for your message. I am sorry you are having this problem. 

Are you saying you generated an image in fast mode. Then you favourite it. Then you later go back to it and want to upscale it. The upscaled image is different. Is that what you are experiencing?  If so, is this happening every time for you? We have had some reports that people have returned to fast mode images to upscale them and when upscaled the image was slightly different. But it does not seem to be happening every time.

Thanks,
