.htaccess redirect issue - robots.txt

Hello all,

Hoping someone can help with this issue with my .htaccess redirect. so a bit of history, I had a Vbulletin (3.8) forum script that had the .htaaccess file you see below, I was using VBSEO (an SEO script that change the URL to be search engine friendly.) I then moved my forum over to Xenforo software, so the threads needed to be redirected as well as my URL - here is the additional code I was given which I just dropped in the top of the .htaccess file.

Code (Text):

1. Options -Indexes  
2. RewriteEngine On
3. RewriteCond %{HTTP_HOST} www.mysite.com$
4. RewriteRule ^(.*)$ http://mysite.com/$1 [R=301,L]
5. RewriteRule ^[^/]+/.+-([0-9]+)/$ /community/index.php?threads/$1/ [R=301,L]
6. RewriteRule ^forum\.php$ /community/ [R=301,L]
7. RewriteRule ^(images|dir2|dir3|dir4)/.*$ - [S=1]
8. RewriteRule ^.*$ /community/ [R=301,L]

The problem is this,
when looking for www.mysite.com/robots.txt it redirects back to www.mysite.com

Please help with this issue, its frustrating to say the least!

Thanks in advance!
