My bots are not forgetting things/ changing personalities

I don't know if this new or a glitch but i've been experiencing changes with my characters memory, when the setting is "Roar" they don't let go of the original conversation that the bot starts with and go on long and i mean huge messages, probably reaching their limit. If you set it in "Meow" then they do listen but give very very short responses sometimes.

Then comes them changing personalities, i change a bot from meow to roar and they completely change, trying to drive their story even if it doesn't make sense for what i've set up previously, like one bot was normal but when i changed back to roar it sent a long ass message and shifted personalities like a human with split personalities.

Overall i want to know if this is a bug, a feature or what not.
