Those who were affected by the crafting XP issue should begin seeing an item in your mail boxes over the next several days. It is very important you understand what this item will and will not do.
The item is single use and will advance your crafting XP one full level. This will only apply to a proficiency level not a mastery level. For example it will advance you through Journeyman level but not Master Journeyman. The item will not advance any crafting past Tier 5 and does not apply to any Tier 6 level crafts you may have. Be aware of this limitation when using your item as we cannot replace any item once used.
