Excessive Townie Generation

Did you port stuff over from the old computer or try a completely fresh user folder ?

Yes I use mods. 

I did remove the entire mods folder, did a new install of the game (I got a new computer recently and it was a good time for a fresh start anyway) and I still get spammed on a new save. I used to, as I said, get the odd new townie now and again. Since Patch 1.16 (iirc the number), I get constantly entire families dropped into my game. I'm not going to a new location (like, say, a gym where I know the game tends to make new townies to attend). I'm staying at home, doing my things with my Sim, going to work in a rabbit hole, etc.

I play on PC.

Edit: So, for example, I just loaded up the game and played for a half hour. I went to "Manage Worlds" and I had 8 new families since I started playing. Not just 8 sims, but 8 families of varying between 2 and 6 Sims. I didn't go anywhere to need new NPCs.

Could you please provide the following information

-  Are you using mods/cc in your game ? Please remove them and test without them if you do.
-  What platform are you playing ?
