[OPEN] [HCHSP] NPC Sims Walk in House After Buying From Food Sale

Hello, I've been playing with the food stand that came with Home Chef Hustle but every time I do a food sale, NPC sims that buy my food go into my house. Of course locking the doors works to keep them out but its very inconvenient and I shouldn't have to do that, they shouldn't come in in the first place. I'm not using any mods or cc and tested in a new save once I noticed this was happening.

Which packs do you own: I have all packs except for For Rent, and all kits except for Bust the Dust, Carnaval Streetwear, Decor to the Max, Castle Estate, and Goth Galore

Please describe in details when you had them enter your home: My sim was running a food sale with the Home Chef Hustle pack's food stand. 

Have you ever used mods/cc on this save?: Yes I have, but when I went to test in a new save I removed all mods and CC (generated a new resource.cfg file as well) and the same thing happened.

Do you have your front door locked?: Only after I realized it stopped if I locked my doors.

Do you have the issue in Rental Units/Houses or Apartments?: In houses, haven't tested with apartments, and I also don't own For Rent.

Do you have the option to send them home?: Yes, I can send them home by clicking on them and pressing the interaction with the orange circle to send them home (and with MCCC mod I could force them to leave).

Did you have a party going on and guests just overstayed their welcome?: Not a party, just running a food sale and they would walk in my house.

Any specific world you have issues with?: No specific world, in my first save I was in Newcrest and in the save I used to test I was in Willow Creek.

Any special type of NPC you have come over all the time?: No special type, but it was a lot of the same townies that came to the food sale.

Did you ever give the Sims coming in a key?: No, none of them had keys.

What are they doing once they are in your home?: After the npc sims buy the food, if I had a dining table/couch they would walk inside with their food to eat. The would also sit around, watch tv, go on my sims' computer. Also, before I removed the half wall, npc sims would go inside just to place their empty plates on the half wall by the front door in my original save.

No NAPs are active in my original save and in the test save it wasn't played long enough for one to become active

thank you for helping me, i started the thread here NPC Sims Walk in House After Buying From Food Sale 

I’ve noticed that using the “convince to buy” interaction seems to turn the Sim you’re talking to into a house guest. If I don’t use it, I usually don’t have issues with Sims wandering around the lot or into the house - they stay near the stand, or go to a nearby table. But if I use “convince to buy” I need to make sure I also select “send home” after they make their purchase - otherwise they’ll wander further into the lot and make themselves at home as if they’re a friend I invited over on purpose.

I also think having the “Send Home” option on a Sim at all is a warning sign - the Sims that I haven’t talked to long and haven’t used “convince to buy” on and don’t wander into the house don’t usually have the option available.
