 Use of wp_cache_get/wp_cache_set in get_plugins in /wp-
 admin/includes/plugin.php prevents a newly installed plugin from being
 detected until object cache is purged.

 By the same mechanism, a plugin directory that has been manually zapped
 from the filesystem is shown as a recently deactivated plugin.

 There's no obvious criterion for invalidating the cached object since it's
 created from a filesystem scan and actively prevents another one
 occurring.

 Perhaps something like a "Scan disk for new/deleted plugins" button on the
 admin page that deletes the plugins cache would be a solution worth
 considering.
