Hi! I tried your steps but sadly that didn't work as well.
I chatted with the help as well but nothing worked.
In the meanwhile I also tried to move The Sims 4 folder onto my desktop and with a new saving file I could modify the lot and play in it, so I fear it might be a saving problem (I tried to recover old saving files but the oldest I can find still has the problem. Especially, I don't know how long this has happened because I haven't played with those families in a while). I also tried to move the family out and back in and tried to enter build mode when one of the lot was empty, but that didn’t work. As well I cannot visit any of the lots or families with other sims.
I hope there is another way to fix this other than ditching the saving completely just for one building complex since I’ve been playing with it for more than 2 years.
Sadly the only recovering saves I can get are the ones of two days ago that the game allows me to load because, for some reason, the whole save seems saved only on a few latest files. For example, even if I have the savings going a long while back, if I remove the files of the last 2-3 days it's like the saving doesn't exist.
So, I fear the only option I have to avoid ditching the whole save is move everyone out of that apartment complex and ignore it. It is particularly annoying since it's 4 whole apartments that are now inaccessible and not a single lot, but I guess that will have to do.
Maybe with one of the next update it will fix itself, probably not.
However, thank you so much for your help!
