This is already fixed for future releases, I'm posting the fix here.
Search:
PHP Code:
require_once(DIR . '/includes/functions_wysiwyg.php');
$vbulletin->GPC['message'] = convert_wysiwyg_html_to_bbcode($vbulletin->GPC['message'], $vbulletin->options['pt_allowhtml']);
Replace by:
PHP Code:
require_once(DIR . '/includes/class_wysiwygparser.php');
$html_parser = new vB_WysiwygHtmlParser($vbulletin);
$vbulletin->GPC['message'] = $html_parser->parse_wysiwyg_html_to_bbcode($vbulletin->GPC['message'], $vbulletin->options['pt_allowhtml']);
Project Tools 2.1.3 will have a compatible fix for every version and 2.2.0 is defined to be 4.1.4+ as minimum version.
