NPCs Stuck in the same place as they spawn

Hi! 

I don't know for how long this has been happening, but I just noticed this.

I started a new game in Bridgeport and I noticed the npcs stay stuck in the same place as they spawn (in front of the buildings their houses are in).

And they JUST STAND there.

It happens too when you get the message "Some neighbours have arrived " or something like that, in the beggining of the game, you know what i mean. The neighbours do come to my appartment, but if i dont talk to them, they just get in the house and stand there until i decide to do anything that involves them.

And no, this is not a 1 time thing, I've started a couple of games and it happens the same thing,

But i have not tried to play anywhere but Bridgeport recently, so idk if it happens just in this city.

I think the sims may be back to normal if i just do "resetsim [name]", but then i'd have to do that for ALL of the sims.

Help please?

Thanks so much to anyone who replies ♥♥♥
