Name: http://www.db.pandawow.me?item=100910/schematic-chief-engineer-jards-journal, http://www.db.pandawow.me?item=100863/pattern-celestial-cloth-and-its-uses, http://www.db.pandawow.me?item=100864/pattern-hardened-magnificent-hide-and-its-uses, http://www.db.pandawow.me?item=100865/plans-balanced-trillium-ingot-and-its-uses.
2. Description of the problem: These objects doesn't learn nothing.
3.How it must work: These objects should teach to produce: http://www.db.pandawow.me?item=94113/jards-peculiar-energy-source (for engineering), http://www.db.pandawow.me?item=98619/celestial-cloth (for tailoring), http://www.db.pandawow.me?item=98617/hardened-magnificent-hide (for Leatherworking) and http://www.db.pandawow.me?item=98717/balanced-trillium-ingot (for blacksmith).
4.Date when I tested it: 02/04/2015.
5.Realm on which you have found the bug: x10 Realm.
6.Priority of the problem: From the view of the profession would be 5, but from the view of a newcomer to level 90 would be 8-9 because these recipes allow learning to engineer, tailor, leatherworker or blacksmith produce armor and weapons better than the contender, and considering that it is disputing the first frame of the expansion 5.x.x and proud the last of it, this would be a great help to them. so I reckon that the priority is 6.
