There are still issues at 920 Medina Studios. I can confirm with a complete clean reinstall (no mods or custom content) that issues still persists after many years. I've played this apartment in the Sims 4 for a very long time and have always found it to be awfully buggy compared to other lots.
- Pets will get stuck in the elevator/another apartment room occasionally when going for a walk to take pets out for potty. This happens when going out and coming home from a walk. Sometimes pets seem too also need to go potty more often than usual (ie other lots). I'm not sure if this is because of the bug not completing the task but the pet will often be sad and asks to go out.
I ended up having to use a "pee pad" mod to combat a lot of these issues. The other way was to travel to another lot with the pet and return back home. This solution is still not ideal though.
- Pets bound as a familiar will follow your sim to work but stay in the elevator whining. This was another solution to pets getting stuck in the elevator when your sim is home because you can teleport them back to you BUT they'll still get stuck when your sim goes to work. This affects the pets mood and needs.
- NPC's seem to still perform redundant tasks in the hall throughout the day. Whether that's checking their mail, throwing out trash or asking to hangout. I notice they also increasingly get frustrated and then tired.
- Random NPCs will appear outside the elevator and then suddenly leave.
- The camera performs awkwardly when trying to view "downstairs" of the apartment complex. I've noticed occasionally that things tend to collect down there whether it's snow, pet waste, or just general trash. Because it's awkward to get the camera to view down there it can be tricky making sure that area is clean.
- When renovating the the apartment the outside of the building seems to be affected as well. The side of the building (with the trash chute) will have it's paint removed off a section near one of the windows.
