Projects and sequences missing or now not saving since update.

To say is frustrating is understatement. Have had zero issues up until last update. Now projects and sequences I have used for over 3 months no longer exist? Have adequate cache, auto save every 5 minutes, plenty of data space.

I am going to presume I had better make duplicate project sequence files on a local drive or I'll have to reconsider workflow as this as it works for me is untenable.

It maybe just me but curious if others have experienced similar issues sine last update of PP?
