As the title says, I've been having random strangers coming into my Sims' house and making themselves at home. I've had 4 unwanted guests already in the span of 2 Sim days. One of them even died and now my Sims have the mourning moodlet! There's no Ask to Leave option when I click on them. I tried using the MoveObjects cheat and put them outside the house but they'd just come back in. One thing that seems to work is the Dismiss Roommate option, which is weird because I never invited them to be roommates in the first place.
I did notice that this started when my Sim got married. The first random stranger was a wedding crasher and stayed until after the wedding. Then she died the next morning. Does this have anything to do with the wedding? Anyone know how to stop this? It's getting annoying.
