Help! Missing CC from game

Hello everyone!

I am on the hunt for my favorite cc wallpaper of all time, that somehow vanished from my game (and computer) with no traces left.

Yesterday I used it and wanted to use it again today, but it wasn't anywhere on my game. I did clean up my cc/mods using the S4MM, but everything I deactivate from there goes straight into my trash bin.

I added every single item from the trash (which was emptied last 5 weeks ago, so it should have been there if I accidentally deleted it yesterday), and still, nothing.

I've done a million different searches on Google and interest, went to some cc creators' profiles and nothing.

I will be forever grateful to whoever can help me find out where it came from and where to download it again.

Below is a real life wallpaper for sale that looks EXACTLY like the wallpaper I'm missing. I do remember it being part of a wallpaper package, and so the thumbnail was not this one, but it was one of the swatches.

Thank you so so much in advance!
