[DU] Sims Get Stuck in the Living Room in Darkwing House

Product: The Sims 4
Platform:PC
Which language are you playing the game in? Svenska
How often does the bug occur? Occasionally (10% - 49%)
What is your current game version number? 1.107.151.1020 DX9
What expansions, game packs, and stuff packs do you have installed? Pack: All except Lovestruck and Crystal Creations. Kits: Fashion Street, Blooming Rooms, Carnaval Streetwear, Moonlight Chic, Desert Luxe, Simtimates, Basement Treasures, Poolside Splash, Riviera Retreat.
Steps: How can we find the bug ourselves? Load into the lot called Darkwing House in Britechester. The more sims you have in the household, the higher the chance that this happens. If someone was sitting in the armchair in the living room the last time you played, the higher the change that this happens. It doesn't matter if the house is set to a dorm or residential lot (I haven't tried other lot types than those two).
What happens when the bug occurs? Sims get stuck between the sofa, armchair, and bookshelf in the living room. It seems to only happen when entering the lot, not just randomly when playing there. I think it has to do with sims always doing things when you load the lot, and if someone is set to watch the TV they might get stuck there.
What do you expect to see? Sims not getting stuck. In other words, some kind of reorganisation of the sofa, armchair, and bookshelf in new save files.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No
