Re: Any way to recover a lot built on a lost save file?

@rolypolyat  The only places the build would be are in your save, in the Library, or in the Gallery.  The Tray folder is where the Library files are located, but you need to actually save content to generate Tray files.  So if you never did that, there unfortunately wouldn't be any files to recover.

At least you probably remember most of what you did to build the house though.  Unlike sims that have to be manually advanced through their lives, you could probably recreate the build, or a reasonably close version, in a couple hours.  Or at least I hope it works out that way.  I know it's awful to lose that much work.
