So..the event is bugged apparently. It’s stuck at “Defeat the Claw of Jormag”. The event tag is up, it shows the dragon’s health bar at 0, but there’s no dragon. And nothing happens. So..no dungeons and no dragon
Claw of Jormag Bugged - Underworld server
This happened on my server as well (Desolation). We experienced periods in which the dragon was un-targetable but would not summon more walls (possibly around the point it got stuck?). After that it never went to a 2nd phase and just flew off at 0% health, leaving the event stuck with no dragon and no chest.
Also bugged in the same way (phase 1, empty bar, no dragon) on Jade Quarry for the last 3 days.
