@DarkestKale sorry mashed the phone while bookmarking this to engage with later. Now is later!
This is something I've seen too, and I love your term for it.
How are you handling your chatbot's "memory"?
Are you feeding it in via a prompting routine (e.g. feeding back conversation history every round) or using a service that does that quietly in the background?
(At this point I'm wondering if one approach is more susceptible than the other.)
