In the quest "Hunting an Ogrim," Nalenteris Brendu asks you to find him an Ogrim to kill and points the way. However, upon reaching the clearly quest-specific ogrim (an initially non-hostile one), Nalenteris does not attack it, nor does he acknowledge seeing it, even after resting near the creature. Meters from the creature, he will still answer "We haven't found the ogrim yet, %playername. You're not quitting are you?"

If you attack the creature yourself, Nalenteris will engage it, but will be angry at you for attacking it first, which seems like it's not the good resolution you are supposed to get.
