From Steam discussion:
I thought this was just randomness, but then I realized it wasn't. When I created a new zone for guests using the Zone command and making it the default for all guests, suddenly they stopped coming for months. The zone name contained brackets and spaces. After I deleted the zone and used another zone, they started to appear again. Also while in a game, changing the zone helped.
