While I can't see any particular reason for a file like that to be
deleted on an update, this error is coming entirely from your plugin.

Examine the error message posted in this thread:

If you examine that code, you have this:

if( $file_found === false ) {
throw new Ai1ec_File_Not_Found( "The specified file '" . $file . "'
doesn't exist." );

That is a pretty horrible thing to do on a production site *if* you're
not catching the exception higher up and handling it gracefully. An
uncaught exception is a fatal error = Instantly broken site.

I would look at all the places you're calling functions that can throw
Ai1ec_File_Not_Found and putting catches around them, to handle the
situation better.
