20 Gladiator
Server - Goblin
Name - Istobar

I got to the point where I am to attend a banquet, once the cut scene was over I was left standing with no new quest or the quest item to attend this dinner.
I am currently stuck on this quest and cant complete or drop it to restart it.

as a subscriber this is frustrating, this is my first class so now im stuck without a mount atm and anything else I am missing to progress the way I need to.

what can I do to correct this problem and continue the game?
