Found a bug. Earlier this morning I was talking in Pocket D, and then had to leave. 12 hours later I logged back in, the people I was talking to remained by the bar where they were. They seemed to be the only ones still remaining who wern't actually there.
Wondering if someone else was in the room that never left and for some reason it kept them loaded in the zone.
Solution found: Leaving the zone and re-entering it seems to clear them from whatever buffer.
