1. Whats bugged? https://www.db.pandawow.me?quest=29475/goblin-engineering https://www.db.pandawow.me?spell=20219/gnomish-engineer
2. How? If you do these quests, https://imgur.com/qOOVGB3 It works, u get them but If you decide to unlearn them once, you can't never re-learn them back again.
3. How can we fix this? Make Goblin Engineering and Gnomish Engineering DAILY quests or actually fix so If you unlearn, goblin engineer for example the quest becomes available again, and same for gnomish.
4. Info you might need? https://imgur.com/EZKTjQV
5. Priority 8/10, very important for world pvp, duels, bgs, etc.
