Snapshot was confirmed finished but not saved - i need to restore site to this afternoon

I had to do a theme update on the site and did a snapshot of the site before to ensure i could restore it if anything went wrong. Well... everything did go wrong and when looking to restore it to a few hours ago, I cannot find the snapshop. Now the site has been restored to the 18th Feb. However i have lost all changes made these past few days. Really frustrated, is there a way to find where this snapshot went? :slight_frown: Many thanks,
