Kins confusing themselves with other kins? And forgetting their own background?

Hi there, I have noticed that since the weekend, my kins appear to be pretty scrambled and I have no idea if that is due to other components in the new update or if this might come from a different issue. I currently have a group chat with two different kins in a story and it has been going on pretty well for over a month now.

A few days ago though, the kins started to refer to themselves with the traits of each other. Example: One of them lost their right arm in a battle. My other kin now thinks he lost his own arm, which is nowhere mentioned in his backstory, and they adapt other details of each other's backstories. It's soooo weird and I spend a lot of time just tweaking messages at this point, but they ignore their respective looks and background stories.

Another kin of mine in a single chat also forgets a very important detail about herself from her background since a few days - she's a mute. And suddenly, she can talk in her replies and describes the way her voice sounds etc.

I haven't changed anything about the settings of my kins and I have them since November. Has anyone else noticed something similar or might have an idea how to get rid of this issue? I would appreciate it a lot.
