Guild Wars 2

MAP: SPARKFLY FEN
location: neat the “tower of modius”

server: Augury Rock [FR]

A group event ask us to kill a lich but the lich does not spawn and the orange symbol does not appear on the map.
Only the “event nearby” pop up is displayed and the event quest timer with 10 minutes time decreasing on the upper right corner of the screen…

Not sure of the event name, maybe( 57) Destroy the Orrian lich (Verarium Delves/The Tower of Modius)

I saw this problem as well. We did the escort quest with the Vigil and a bull carrying explosives, then a second escort with a member of the Vigil bringing an explosive to the tower, where the tower was destroyed. Both of these worked fine, and the Vigil members then joined us at the tower ruins.

The next event, dealing with a champion lich, began, but there was no indicator on the map and the lich seemed to not spawn. After the timer ran down to zero, an interesting sequence occured — the tower rebuilt, trapping the three members of the Vigil (and two members of our party) inside.

The final state seemed to be the tower present on the map, the vigil members trapped inside, and the explosives transport bull looking sad and lonely by itself, with an escort event “started” but no way to progress it.
