Houses/Lots Disappear

That’s actually a different thread, the furniture thing is this one https://forums.ea.com/idea/the-sims-4-bug-reports-en/floating-furniture-and-building-completely-gone/11884329

Like I said....Every time I start a save, after awhile, my lots start disappearing when I load into them.  I was just showing that these other things start happening as well with this bug.

This has started happening to me as well. I spend three hours building a normal residential lot, only to have it disappear when I try to reload the lot from manage worlds. I can still see the building on the map. As I hadn't finished the build I haven't saved it to my library yet. I do have mods and cc in my game, but everything has been updated or cleared for the latest patch. I hope this isn't going to become a regular issue, as I've been working on this save file for a while now, and it would be heartbreaking to lose it all because of a bug. 

So this is happening to me as well, and it is consistent, I've backed up my saves, I go through updates and test without mods. It's not every world but it is several. In order to see it I guess there needs to be significant data in the saves themselves. I've repaired the game, I've reset the sims 4 folder, I've uninstalled and reinstalled. I've gone back to previous saves. Is the saving system not equipped to handle all that data? I've even done the scratch folder method, and nothing is working. Considering it's pretty pricey this is an insane thing to happen. I am so disappointed because I would have to start over. I have rebuilt all the worlds, except for the last two expansion packs. I've given all the townies makeovers. I hope there is a fix for this soon, I'm not sure if it's because I used backups but originally I just used the main save I was playing on I only went to a backup because of another bug I had to deal with that was fixed with a brand new install. So if the problem lays with using backup saves? That's also disheartening because it means a save file can become "corrupted" at any point in time in an arbitrary fashion.
P.S. All of my builds use in game items no CC. 

This has happened to me too for the first time.

I spent 2 hours building a new lot on the "Casita Del Amor plot in Ciudad Enamorada. I shut the game down for a while before returning to finish the build. The lot I built is showing when I load the map view of the world but when I click on the lot and enter in build mode the lot reverts back to the default build that released with the game. This is a new save which i've only used for building, not gameplay.

I have tried the following without success:

1. Recovering the save to an earlier version
2. Removing all mods & repairing the game
3. Clearing cache and restarting the game
4. "Saving as" to create a new save
5. Entering the lot in live mode in both the old and new saves

I do use mods 

It's likely connected to For Rent, but lots of people have reported it spreading across different lot types and worlds. It usually starts in Willow Creek.

This is still happening to me..., what info do you need? I can help

I just put a bunch of small businesses in willow creek and new crest and they all reverted back… yall…We deserve better. Sucks we’re treated like this as players and still expected to invest into this game with broken features since launch… just sad. Like I’m shocked is allowed without repercussions.
