User blog comment:Sims3Fan33333/Kaylynn Langerak in my custom neighboor?!/@comment-75.5.244.8-20130824185933

All Pleasantview NPCs such as Kaylynn, Gopp, and others are the default NPCs for custom neighborhoods so no it's not a glich or a bug. If you want to NPCs look up a tutorial, I hope this helped have a nice day. :)
