I saved every 20 minutes... On a 7hr build...
I was inspired by Love Island's epic fail of a season. I decided I could do better, then spent 7 hours today building my Villa. I saved every 20 minutes and even shut my laptop a few times throughout...

Try restoring a previous past save and seeing if the build still remains in that save. I hope it is there as it would be upsetting for you with all the work you put into your build.
