Include in VirtualHost disappearing after rebuilding httpd config

Hi,

I have a client who has a JSP servlet instance, and we have an Include in his VirtualHost file that maps the requests

Include "/usr/local/apache/conf/userdata/std/2/custom/customerexample.com/*.conf"


It seems that even though after modifying /usr/local/apache/conf/httpd.conf to ensure this is there,

then running /usr/local/cpanel/bin/apache_conf_distiller --update

It ends up some how disappearing.

I've also tried
/scripts/ensure_vhost_includes --user=customer
and
/scripts/ensure_vhost_includes --domain=customerexample.com

But they actually just seem to break it altogether, so I'm obviously not doing something right.

Any help would be greatly appreciated.

Many thanks
