BTW this horrible hack fixes the move issue... (I edited the product file)
Code:
<plugin active="1" executionorder="5">
<title>modpm :: Standard :: Thread :: Move</title>
<hookname>threadmanage_move_redirect_orig</hookname>
<phpcode><![CDATA[require_once (DIR . '/includes/class_modpm_checker.php');
require_once (DIR . '/includes/functions_modpm.php');
$savethreadinfo = $threadinfo;
mod_pm($threadinfo['threadid'], 'move', 'thread', $foruminfo['forumid'], $destforuminfo['forumid']);
$threadinfo = $savethreadinfo;]]></phpcode>
</plugin>
<plugin active="1" executionorder="5">
<title>modpm :: Standard :: Thread :: Move Simple</title>
<hookname>threadmanage_move_simple</hookname>
<phpcode><![CDATA[require_once (DIR . '/includes/class_modpm_checker.php');
require_once (DIR . '/includes/functions_modpm.php');
$savethreadinfo = $threadinfo;
mod_pm($threadinfo['threadid'], 'move', 'thread', $foruminfo['forumid'], $destforuminfo['forumid']);
$threadinfo = $savethreadinfo;]]></phpcode>
</plugin>
