"Our Plugin" is http://wordpress.org/plugins/all-in-one-event-calendar/

I haven't heard of any other plugin having it's content in wp-content 
whacked by the update. I added this to the master list though.

In general, it SHOULD be impossible for WP to delete anything like that. 
It has a very specific list in wp-admin/includes/update-core.php of what 
it deletes. Look for the _old_files array.
