Missing Media Files for These Clips
After 2 days of editing and my video at 99% completion, most of my audio files have gone missing.
I'm a constant 'saver'. Saved my project repeatedly. Upon re-opening my project I get this message:

Now, I've closed and opened Premiere many times during the last 48 hours and NOT had this happen. I have NOT deleted any files or renamed any folders so I can't fathom why these audio files would suddenly go missing. I did a search for the missing files and they are not to be found anywhere.
If I can't somehow figure out what went wrong and fix it, my only choice is to waste an entire day re-editing the video. The scary thing is I could do that and this could happen again.
I did a search for one of the files on my entire computer and the only reference that came up was a matching.pek in the P:\Premiere Cache\Peak Files folder. This gives me a worrying suspicion that my audio files were living in a temporary Premiere cache which maybe auto deletes after a set period.
Can anyone save me from jumping off a bridge?
Thanks in advance
Gavin
