I have had the most frustrating time lately. Every dungeon quest that I have been on lately has been reseting itself on me when I am killed and returned to commons. Then when I return to the quest site whether I have a teleport mark, or not, they seem to reset themselves. Like the counterwieght east Old Smokey quest. It is so frustrating.
I too have had that problem with getting killed and then going back to find the whole dungeon reset. So far I haven't had that problem when I port out to heal and then port back in, only when I die.
A couple of days ago, this happened to me in Crismon Field, A quest to fight the War Oni was pointing out of crismon field, then i went out, when i went back in a second later, i had to restart it
Dungeons are personal adventures. They must be completed to get full credit. Logging out, leaving through the Dungeon entrance, or going to another dungeon will reset the Dungeon you started.Going to a PvP match or going to your Castle or Dorm room will reset the dungeon. Leaving any other way gives you 30 minutes to return before it resets. Up to four people at a time can be in an Dungeon.
