[F] Merge posts - attachment(s) problem [R] [C-Michael83]

[Michael S.]

It's 1 before the merge. The reason for the change can be found in the function merge_posts():

$query2 = $db->simple_select("attachments", "COUNT(aid) as count", "pid IN({$pidin}) AND pid != '{$masterpid}' AND visible='1'");
$attachment_count = $db->fetch_field($query2, "count");

$db->update_query("threads", array("attachmentcount" => $attachment_count), "tid = '{$mastertid}'");

$masterpid is the ID of the first post and because of that the query returns 0.
