met rosalyn on her way to the bathouse, had a conversation with her and invited her to go have lunch at the tavern, i realised then her current priority was to go to the bathhouse as she started a new dialogue to decline, but the moment she finished presenting her message, it would close and a new one would appear, this repeated constantly in an infinite loop, probably a bug
This is a known issue that arises when an NPC tries to follow you while on their way to another map tile, in this case Rosalyn going to the western mountains.
I'll release a fix for this soon, but I'm also waiting for Alibaba to present their new model family, in order to bundle the bug fixes/a potential better <10 gb vram model into one patch, if it turns out to be better than the previous one.
