Random visits (solved)

You'll need your Sim to open the door and ask them. Hope you speak simlish.

It's not the welcome wagon. I'm getting so sick of these people just turning up on my doorstep.

@Stormkeep I'm already using 3 lot traits and that doesn't really get to the root of the issue. Why are random Sims just showing up at the door? Sims my Sims have never met before shouldn't just be showing up on the door step.

@LolaLuvsSims, I get what you're saying...and don't really disagree. The lot trait was put in for the segment of the player base who doesn't like the random drop-ins, can't really blame the devs if you do not want to use it because you want 3 other traits.

There is a mod out there that lets you add more than 3 traits to a lot if you want to go that route to help yourself.

You keep responding @Stormkeep but you're not actually answering my question which was the point of this post. My Sims know all of their neighbors but the only Sims who visit are random strangers

I'm having the same problem. and they don't knock, they just walk in. even when my sims have asked them to leave, there still there watching TV, taking a shower or helping themselves to my sims food in the fridge. My sims have enough friends, if they want to meet someone new they can go outside and do so. I wouldn't want a stranger in my real home, taking a shower, watching my TV and eating my food, I certainly don't want it in my game. and I don't want to give up a lot trait because of it either, it just should not happen.

It sounds like a bug to me if it's complete strangers. On launch it was only Sims we already knew or the Welcome Wagon.

It seems like they are vampires. I can't say that was true for every one of them but the last few were vamps. They just knock and stand there.

They might be the Welcome Wagon that welcomes new playable Sims to the town or just random walk bys that have happened since the first Sims game.

@lolaluvssims Add the "private dwelling" lot trait and it should stop most, if not all, of the visitors. You can still invite people over that you want to have visit. That's the whole reason they made that lot trait.
