Vanaduke disappeared

During his first phase, while me and my friend Espeonage (I was on my character Zettalux) were fighting him, he just DISAPPEARED into thin air. It has been an hour since this happened - we've sent reports to game masters and reported bugs. We're pretty much stuck in an empty throne room. We killed the remaining slags after he disappeared, and nothing else spawned.
We paid 10 CE for this -.-. We've put a lot of our time to go through all of T3 only to be stranded at Vanaduke. Yeah, imad.jpg.
"Where'd this beard come from?" - Espeonage

We DID send a report. We did that almost right after Vanaduke disappeared - more than an hour and a half ago. It happened at approximately 1:50am EST. It's 3:32am now D:

While I do understand there is a thing we love known as sleep, I'll admit that I was disappointed for once.
If no one has these work hours, then the timeframe(s) should at least be noted somewhere - somewhere for all to see, and/or perhaps warned that no one will be able to assist you during this period.
In the time that we waited, we could have done another run and have been battling Vanaduke again; the whole charade ended up being a waste of time, and energy [with all meanings intended.]

i guess it wasn't just us, yes we feel your pain, and he disappeared on us too
We are waiting lil longer then eventually gonna giveup...
5:12am and counting...

Couldn't wait anymore, especially after seeing your topic, wasted trip down to Vana for both of our parties.. awaiting at least a response...
and our topic just to add it out incase this is seen

I, too, would like to know which hours GMs are actually active.
Here is some footage in case one of the devs is looking for the source of this problem:

I sent a ticket and got help from a gm withing 10 mins. Took a while to reset the fight though.
EDIT: just re-read you post carefully and saw you already sent that mail.
Whoever's on duty should be able to sort you out.
