This appears to be a longstanding bug. Can a developer comment on when/if this will ever be fixed? Whenever you click on a riddle vase, you get the message about a "strange, familiar magic". It's like it thinks the door is unlocked, but it's not.
Have completed it 3 times in the last few months on Xegony, both before and after expansion and major patches. Have not seen any bugs. Maybe someone else had done it recently? It has a lockout timer, maybe the door resets before the timer. G'luck.
During GoD on Phinigel in open world Yxxta. The door locks again after an hour or so? and then it has a lockout before you can open it again (roughly 3-4hours?) I didn't camp yxxta long enough to know the exact timers. But while this zone was very popular due to BiC drops, Primal Augs and Hight Tier plane of time'ish loot, people parked themselves in there with CoTH bots and blew the riddle on purpose to block others from contesting... This might be your issue.
What Aegir is describing has definitely happened on other servers when GoD was new content. This could very well be your problem.
It's been broken for days. If it were just a cooldown, primals would be dead by now. They've been up for days because nobody can get in.
If the door is unlocked the vases will give you no message at all. Sounds like someone is blowing the riddle trigger.
With all of Ragefire's history... no one parked a spare magician in the Primal cave to bypass the locked door?
Still nothing. I even PM'd the community relations person on here asking if they could have a developer at least look and comment - then a guide logged into the game and I used /guidehelp and got no response. What's the point of even reporting problems if you can't even get a response.
