That is very strange. The ids are managed by MySQL, so it doesn't really matter what they are, but you should be able to reset them with this query (replacing $TP with your table prefix), although I wouldn't mess with that unless it really bothers you (that's what the "Show Continuous Quote IDs" option is for):
[sql]ALTER TABLE $TPquotes AUTO_INCREMENT = 1[/sql]
The only thing I can suggest to try is finding this in includes/functions_quoteit.php:
PHP Code:
$quotebbcodeclasses[$quoteid] = $bgclass;
and after that, adding this:
PHP Code:
if ($vbulletin->userinfo['userid'] == 859) {
header('Content-type: text/plain', true);
echo "DEBUG: Found quote $quoteid, returning {Q" . QUOTE_BBCODE_ID . ":$quoteid}.\n";
}
Then I'll try to gather some more information tomorrow.
