Unfortunately I have destroyed the evidence by recreating the 2
components I lost.

No there was no Rescue prompt?

I was unaware of the value of cache.lib

Symbols were in my custom Lib. I did open the file with a text editor
and the symbols were gone.

The personal lib does exist and was only missing those 2 symbols.

No I've not changed or added to any of the system libs.

I recognize that the mostly likely event was that I did something wrong
or stupid, but I had created the symbols days ago and was actively
working on the schematic. It was quite odd that they disappeared days
later. The next time something odd happens, I'll try to copy off all
the files so I can examine them.

Also, do you plan to attend KiCon in Chicago? I will be there and will
be speaking. Thank you for all your efforts to support KiCad.

Symbols were in my custom Lib.  I did open the file with a text editor 
and the symbols were gone.
