Household Sims walking through doors locked to them

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 on (PC, Mac, Playstation, XBox)
• Have you tried turning the door around ?
• It's also best if you edit your post and make a thread about the animal locks in the feedback forum.

I don't use any mods, I play on PC. The way the door is turned does not seem to make a difference. 

It also seems impossible to edit my post, there are no three dots there to click on.

HI thefirsttemplar​ 

is this household members only or also NPCs ?

Alright, edited. 

I've not seen visiting NPC's do that yet, but I don't often have visitors over. 

Thank you. Setting this to review then but I did find something similar: [BH] Sims ignore Door Lock settings at house after starting a small business | EA Forums - 12589855 

Do you also have a business ?

No, I haven't used any small businesses yet and this problem already happened before I got the business and hobby expansion. 

I just have four couples starting out in a regular home, sharing a living room and kitchen, and each pair having their own large bedroom with room for some things for their hobbies and their own bathroom. I added an extra room when a couple divorced, I am mainly running an experiment here to see how the worst possible couples with opposing traits and interests work. 

Only one has an active doctor career, the other seven have regular careers. 

The trespassers have moved in to clean up things, use an object in there like the yoga mat or a computer, or to talk to a sim who is in there.
