Zana mission bug (maybe Einhar influence)

I was doing Wharf and Zana apeared, got her quest and went to Bazaar map to do her quest, cleared the map, found the "Essence trapped mobs" and they were mobs of Einhar quest, so I killed them all, and found myself stuck with 14/16 mobs to clear (from Zana quest log).
Time is over, got a fail on her quest.

TLDR: Zana Essence Trapped Mission 14/16 with 0 mobs on map.
