Okay so I can shed some light on this.
Currently if Player A is in [Solo] (not enrolled in VvV), Player B is in [OC] (enrolled in VvV), and Placer C is in no guild at all. Player A cannot heal Player B anywhere at all - Trammel, Felucca, Malas, etc. Player B is always treated as "No beneficial acts can be given to the player". Player C being in no guild can still heal both Player A, and Player B.
That's the main bug I ran into with the notoriety.
