Gmod save with no content

I spend hours making a gmod save today. When I finally completed it, I saved my game and 10 mins later gmod crashed. Anyways, I log on again, load the recent save I made, no content loads or previews… I spent hours making my save on big city and when I load the save nothing shows up. I don’t understand why its doing this when the save thumbnail shows content on the picture.

The second thumbnail is the save I made.

Gmod saves have been fucked since Gmod 13, you’ll have to wait till Garry fixes his shit.
