I had a similar experience which I described above. I think you've stumbled onto the closest thing to proof that Day/Night is not necessarily a universal requirement. The one consideration that I'm not sure does, but may affect your observation is that based on what I wrote up in the Aug 2013 update, it appears that the information may be saved in the Pawn's server file, because I was able to release and rehire a Pawn with full knowledge even though the owner had not yet rested to receive the update. This doesn't happen with equipment and the like and, I think, not with Bestiary Knowledge, but it did happen with the Gransys 3rd star for some reason.
