That link I posted contains a list of recipes that require skill '75' for combining.
"9909,Pieces Of The Iceclad Map" is in that list.
You can run this script on your database to find ones that may be affected on your server:
Code:
SELECT `id`, `name`, `tradeskill` FROM `tradeskill_recipe` WHERE `tradeskill` = '75';
Off the top of my head, I really don't know what it could be since the default server appears to be working..though, it is an intriguing issue.
