Thanks to those that reported some smilies and Avatars packs that were no longer downloadable on the posts!
Also a big thanks to those that re-supplied them so I could go through and edit the posts to re-add the packs (Ashley, cisco, aldenbaker and anyone else who I may of forgot)
At the time of this post, all missing avatar packs have now been replaced and will be looking at the smiley packs in the next few weeks.
There seemed to a problem of some attachments just going missing from posts and was totally confused! That is, until I read this http://www.phpbb.com/bugs/phpbb3/42815
Apparentely, this issue has now been fixed in the latest 3.0.5 version so that is another reason for people to update when it's out or you could end up being in the same position I was with the attachments!
