Guild Wars 2

We have been trying to finish killing Zhaitan, however Zojja will not do anything. we do not want to restart it (since we all hate this stupid dungeon on Story Mode) but wave after wave, the Asuran Genius is having a bit of a brain fart.

Can some dev say this is not a bug and working as intended or is Zojja getting lazy?

Just did the last story mode quest as well. Endless waves of risen (same with last three dragons prior) and zojja just stands around and no weapon charging progress. Sometimes she will just follow players to the waypoint below deck.
