I too monitor Bella's profile in the hope that she might return.
As she done anything to her profile, it looks like the latest login was just doing enough to keep her profile active and not shutdown by AW. Can only speculate that there is something in her life that prevents escorting (illness? potential partner?), but she doesn't want to lose the option to easily return.
Anyway, hope Bella is well and happy. She was a fun punt.
