Missing Engineering Profession Skill - Urgent Assistance Needed

I am writing to bring to your attention an issue I have encountered in World of Warcraft, specifically regarding the disappearance of my Engineering profession skill.
Character Name: Yujirosmom
Realm: Onyxia
Description of the Issue:
Recently, I noticed that my Engineering profession skill has disappeared from my character's abilities and professions list. I have invested significant time and effort into leveling up this profession, and its sudden disappearance has left me unable to access its benefits and features.
Importantly I have leveled it beyond skill level of 225, which probably should not be possible for my level 29 character.
Steps Taken:
I have already tried the following steps in an attempt to resolve the issue:
Logged out and logged back in.
Checked for any relevant in-game notifications or error messages.
Verified my character's professions through the in-game professions tab.
Restarted the game client.
Despite these efforts, the issue persists, and I am unable to use the Engineering profession abilities.
I kindly request your assistance in investigating and resolving this matter as soon as possible. The Engineering profession is crucial to my gameplay experience, and its absence is hindering my enjoyment of the game.
Please let me know if you require any additional information or if there are specific steps I should follow to help expedite the resolution process. I appreciate your prompt attention to this matter and look forward to your assistance in restoring my Engineering profession skill, at least to the skill level of 225.

Please do something about this. I haven't played wow in such a long time and I didn't realize that i was using a bug when i bought artisan skinning. I mean my druid is lvl 33 it's not like i was going to use it to exploit or anything (can you even abuse skinning... really ? you have to kill the creatures to skin them...), i just saw it at my trainer and thought "cool i'll buy it already that way i won't be max level and skin for nothing"...

I really don't mind if i get it at a lower level than it was, I just really don't want to go through the trouble of skinning all those low lvl creatures to lvl up skinning again just so I can finally skin the creatures that are my level again...

Didn't artisan require you to be level 35?

"Apprentice (1-75) can be learned from level 1.
Journeyman (75-150) requires level 10.
Expert (150-225) requires level 20.
Artisan (225-300) requires level 35."

People exploited it. Warmane is doing a cleanup now.

A lot of us didn't exploit anything. We just clicked on something that was green at our profession trainer without thinking too much and now we're fu****... I really don't want to lose hours skinning low level animals just because of this bug. My character was 2 lvl away to actually be able to learn artisan skinning anyway and now it's gone just because i was too stupid to know it was bugged.

I also have the same problem with my engineering skill, its messed up to just delete profession instead of downgrading it as i didnt even knew it shouldmt be able to level past 225 at level 30

Because the mistake was from us, none of you got banned. But that doesn't mean we will leave you with the contents of the exploit. Sorry for your wasted hours.
