I reloaded a couple of times to find out when exactly this happened, and it was two conversations after Anomen's knighting. Not the one right after the knighting, which triggers upon leaving the Radiant Heart building, but one that occurs a little later on where he thanks you for your help (I'm sorry, I'm not sure how to look up which Lovetalk that is!) No matter which response I chose, it got set to "2" right after that. I noticed Keldorn is still starting conversations after that point, though.
