Is there a way to recover a build from tray files?

@r8dhvgqxnda4 You could also check the trash on your computer and see if the save file is still recoverable - or check a backup if you backup your computer. The build is only recoverable without the save if you had also saved it to your library. I generally save any and all lots I'm happy with to my library, even before I start playing. Then I just go through the library later and might delete things I'm no longer happy with, have too many of, or that were built with mods I no longer have.
