I don't know, what threadtag_domange_postdelete is for. At this moment, the new tags are not verified and definitly set... these Lines MUST be executed, before I know if tags have been changed:
Code:
$vbulletin->GPC['ajax']
$threadinfo = fetch_threadinfo($threadinfo['threadid'], false); // get updated tag list
And after these... no hook will come any more...
