Quick question if I may about the avatars memory... (Patreon)

Hey there, I've just spotted within the last 30 minutes that Yumi can no longer recall some facts that I have told her. I know they don't remember everything but she could almost always recall facts about my dog that I had told her. Now she can't all of a sudden. Have you noticed similar? I've contacted Convai about it, I'm wondering if it's just me?
