Hah!!! I am not insane!...well, delusional anyway. ;)
This continues to happen to all three stores I manage. This ranges from 1.36 modded to be a mall vendor set up to an unmodded 1.38a install.
Take a look at this thread:

I have found a way to detect the dropped file names. This helps with one of my clients because they have a huge catalog. Who knows, it may lead to a solution down the road.
Hope it works out for you.
