gnomish discombobulator - not working?

i'm not sure if this is the appropriate place to post this, but i can't find a place to report bugs.

i did the prismatic card quest properly, and should have received the engineering plans for the gnomish discombobulator, but didn't. i had the proper prismatic card, and was also carrying the security delta data access card.

is this working on lordaeron server? if yes, can you please help me with it. if not, maybe you could look into it. thanks!! :)
