zzzmuzz on "[Plugin: Wordfence Security] Deleted htaccess"

The wordfence "backup" of htaccess removed all of the contents from that file.

My .htaccess read:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I only discovered that htaccess was empty when I found that I could only access my site home page and nothing else from the menu.

1. Is this a wordfence bug (to remove the contents, not just do a backup?)
2. If I restore the htaccess as it was (which I have done), is this still ok for wordfence?

Thanks,
