Perhaps because one guard saw me upstairs? I I managed to take him down with a sleep dart and get rid of him before he could raise an alarm, however. I was able to to my task and walk out of the mansion as if nothing had happened. And I always thought, as long as the party guests are still wandering around instead of cowering, and the guards leave you be, everything's just fine for the achievment.

Still it could be just be a bug, though. My Food Chain achievment would not unlock until a friend, whom I let do a playthrough on my account killed his first assassin. And I had killed dozens of them before without getting the achievment.
