My first bug :'(

So, when you got a moved topic and you create a "shadow topic" there isn't something wrong. But when you take a look on the active topic list of that forum (so in the category) the shadow topic is showed, i think it doesn't make sense to show a shadow link.

And I got also a debug error:
[phpBB Debug] PHP Notice: in file /viewforum.php on line 465: Undefined index: forum_mark_time

Tested whit MySQL 5 and PHP 5 on Windows XP Pro.
