Unable to do Goblin engineering. [WOW Classic]

I am unable to pick up Goblin engineering quest upon abandoning gnomish engineering, and relearning engineering back to 200+ I am level 60 with 203 in engineering right now.

Update: Now engineering is sitting at 255, no quest available. Neither Goblin nor Gnome engineering quest is available.

Have you tried posting in Classic Bug Reports? The support you’re likely to get in the Retail support forums is pretty limited.

Thanks. I was linked here using the in-game submit a ticket option within classic client. I think this is the actual bug I found. It turned out that you can relearn specialization by reading a book.
