If you go to the bots group in memberlist.php the bots are not listed.

I have no idea why it is setup like that, it was displaying correctly a while ago(before B2 when I checked it last).

But anyways, it is a pretty easy fix...

Open
includes/constants

Find
//define('USER_BOT', 2);

Replace with
define('USER_BOT', 2);

Open
memberlist.php

Find
$sql_from
WHERE u.user_type IN (" . USER_NORMAL . ', ' . USER_FOUNDER . ")

Replace with
$sql_from
WHERE u.user_type IN (" . USER_NORMAL . ', ' . USER_FOUNDER . ',' . USER_BOT . ")

That worked great here.
