Mystery of the missing file

Hi,

One of our suppliers upload scanned files for our organisation to SharePoint. 

One of the files has been uploaded  yesterday and was visible on the SharePoint site yesterday. 

It has mysteriously disappeared!

I have checked the audit log, see 1.png attached and it is logged as uploaded, no move or delete events. 

When i click on the Object Id link, see 2.png, I get 404 NOT Found

Any ideas?

Thank you for your time,

Ollie
