Is there a mod that stops sims randomly showing up in holiday worlds? Reason Im asking is one of my sims decided to take their latest squeeze on a getaway to Granite Falls. Their ex with a grudge, Katrina Caliente showed up and started a fight. That was totally hilarious, but not what I was planning. Reason for the getaway was to get away from her.
