I'd like to report missing standard BI Reports???

Summary

A search for my standard BI Reports shows 'no results' and around 20 of my custom reports are gone, also?

I've been working in reports all day; created a few new custom BI Reports; grabbed some coffee and came back to find that I now have NO STANDARD BI REPORTS??

A search for my standard BI Reports shows 'no results' and around 20 of my custom reports are gone, also?  (see screenshot)

If this is a trick, it's a nasty one!  Has anyone every had this happen before?

Oh, and I've cleared my cache, too.  Still no dice.
