Locked doors unlock themselves when leaving the lot

Also confirming that I've been having this problem, too, particularly in City Living apartments. I tested it without mods, in three separate households. 

I've also had random, uninvited Sims coming into the apartment, as a result, even though none of them were given a key and none of them had ever met my Sims before. 

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What is your current game version number? 1.89.214.1030
What expansions, game packs, and stuff packs do you have installed? City Living, Discover University, Island Living, Cats and Dogs, Vampires, Werewolves, Realm of Magic, Tiny Living
Steps: How can we find the bug ourselves? Lock the door and computer specifying only two people can open or use it. Then, travel somewhere and come back to lot with the door and computer.
What happens when the bug occurs? I lock the door and computer for certain household members to enter a room and use the computer, I travel with one of the sims to a different place, then I come back to see that a sim that I had locked the door and computer to prevent them from entering and using is in the room and using the computer, even though the lock for the door and computer had not been reset.
What do you expect to see? Doors and computers should stay locked exactly as left when traveling and coming back.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

I would like to not have to relock doors and computers after coming back from traveling with a sim.

Can anyone experiencing this issue possibly share a save file where you've seen it occur? Thanks so much!

I this now The thread to post about this issue? It's weird that there are so few Me toos in the thread... This is a nightmare with random sims but also roommates barging into your house because those "only me" or "only household" (or any) lock states don't stick to the doors. This includes the highschool windows! If you remember to relock the door but not the windows, townies will crawl in from the windows argh 😭😭😭 

This would be kinda funny if it wasn't so annoying as I like to actually leave the house when I play. :/

Please send your save to Simguru Nick if you play vanilla so we can one day get this fixed! I'll love you forever if you do!

I'm having the same problem too. I play on PS4 and have no mods or CC. Everytime I leave my lot and come back, all my doors have somehow become unlocked. When I clock on the door, it appears that the lock is still in place (one of the options that shows is "Unlock"), but random sims are able to walk through the doors.

Every time I come back I have to click on each door, click unlock, and then reset all my settings to the way I want them. Once I do that then sims I want to stay out are no longer able to enter through the doors.

Very frustrating as I have quite a few doors that I have to reset each time. It certainly makes me want to travel less which is frustrating because I feel like I'm missisng out on a huge part of the game this way. I hope there can be a solution to this glitch soon
