I don't have the exact date, but I think it was summer of last year. I posted on a guild forum about it in August of 2007. This was probably a few months after starting the quest.
I opened a petition, as you suggested.
The problem is not knowing whether the quest is bugged if you do not know the answer when giving the riddle to Vlad or if I have not found the correct trigger phrase. I have tried multiple keywords, using the keyword by itself and about [keyword] formats.
I tried the in-game help feature in August of 2007. I was attempting to either find out the single correct trigger phrase or find out if the quest was bugged. Each request was met with a response that they were not allowed to help. It would seem that using the help tab would be preferable to an ooc request of Ojaveda at large for help with the quest. One of the responses was that the help tab did not give spoilers, ask in game. Another was it was only for tech problems, but the helper immediately closed the help request and I was unable to find out if it was a technical problem with the quest or I had not stumbled across the correct phrase yet.
Can someone tell me if the quest is bugged? If so, is it on the bug tracker?
If not, could someone send me a private message with the trigger phrase?
