Undoing an autosave after the file is closed?

[Burnsie]

So, I transcribed an interview on Word. It's saved to my OneDrive so I can access anywhere, but usually access from home through the usual program (ie not 365!)

I saved that interview

On to the next one and I use the first one as a template

I somewhere saved the new one as interview 2 (that's fine) and went back to the first one to start editing it again (interview 3)

But somehow, just as I was closing the document I was working on, I noted at the top the file name said interview 1..."saving"

By then it was too late and my interview 1 file is now the same as interview 3. As I closed it I can't undo and resave.

Any ideas before I have to re-type the whole interview 1?

Try the Version History in OneDrive (https://onedrive.live.com). You may be able to find the lost version. 

The thing about OneDrive is that you can't use Save As to transfer the most recent changes to a new file. The automatic saves will incorporate changes into the current version of the document.
