I play on PC and have been encountering this. I have all the bedroom doors locked for everyone but the specific sim(s) assigned to that room. The locks seem to work, at first, but then other sims in the household that should have no access to the room are suddenly able to go through the locked doors. I have checked the doors and they have the options to unlock for the sims entering, showing that the lock is there but the sims are ignoring the lock. It's quite frustrating as I have to reset the locks and I'm not sure what causes them to ignore the locks.
What seems to be happening is the game decides to route a sim to something behind the door, like a computer (fav target for sims), before it has decided if that sim can actually reach the object, then POOF MAGIC! when you're not in area that sim has been allowed to reach the target anyway with game being like -well screw that lock- and then when you look the sim is now locked behind the door which game now realises actually exists...
If you use a mod to lock the offending item eg computer from all other sims the lock "stays locked" to randoms, because that attracting item inside room is no longer overriding the door lock's power (or more precisely order of operation).
Note that this is a completely different issue besides the door locks deciding to just not work at all after sims have left the lot to go to work etc.
I have notice it with angry sims wanting to knock my garbage bin. I made a purposefully enclosure for my poor garbage bin outside and lock the door to only household members, turns out an npc came long after I locked the door, and got in to knock my garbage and was then stuck inside... I can of like this bug as for their naugthy behavior toward my garbage bin I can let them died of starvation lol.
I just want to clarify, when I say long after I locked the door, I mean like irl days, so I did that enclosure and lock it, then play in another households etc... and then few days later I go back into that family and this happen. Just so you guys dont think I did lock the gate, and a few hours sims the npc came and did that assuming they might have queued the action before I lock the gate...
