Why are non-Henford sims obsessed with talking about the Henford villagers?

@mightysprite The deletion has worked actually, but I don't know how long it will last. I forget to mention that I don't play with mods in this save game and don't allow moving into empty houses. I deleted the villagers and a bunch of townies, but not all. Then I've got an invitation for the spice festival by J Huntington. My sim has talked to a lot of well known but for her unknown sims, and nobody of them had mention HoB, unlike before. But as wrote I don't know how it will last, I guess as soon as I visit the village, it will start over again.
