I was doing a quest in the wild, and I was doing the dungeon with the four giants with two other wizards. I completed the quest and got some reagents and treasure cards, but when on my quests, it still said I hadn't finished it, can someone answer this for me
Did you teleport to a friend to get into there? If so, then I see the problem.
This happened to me a few times in Celestia, where I would accidentally teleport to The Commons of the world by pressing the 1 key when trying to move right, then I would teleport to my friend on battle.
The thing is, you didn't let the Boss say it's speech, the only thing I know how to fix this is go in, let the Boss say it's speech, and re-battle him.
