Were you using your main character at the time, or still controlling one of your companions after a fight? Because they'll usually talk to the currently-controlled character.
If that is true, then system must have ben somehow updated ...
Since as far as i know, every NPC i have seen allways started talking to closest friendly PC it found.
I don't mind this at all, personally. If that happens, I RP the answer as the companion would answer it, which sometimes leads to hilarious results.
It might not be a problem from roleplay perspective ...
But it can block you out huge deal of aproval from some characters, if that is happening often ...
