Not from my experience been playing this since 0.35 and it has always been random between 2 men and a woman or 3 men.this is the 0.39 change, until 0.38 there was always the girl present
I've had this encounter nearly 30 times never had only 2 men, always had 3 men or 2 men and a woman although out of those I've only had a woman show up with the men 3 times so it's probably only a 10% chance you'll have one show.While walking close to the city border three attackers jump out of the corner", its only 2 now and all males, it was random and males and females.
