dungeon

After last update (around 15 Feb), I can't complete any dungeon.
My level is above requirement and my location successfully reached the dungeon according to both map and last event messages. But it's liked passing with nothing happened, neither boss nor achievement.
I have tried several dungeons (Pinnacle rocks, Hellfire chasm, Giant tree), but results were same.

Moreover, the statistic about boss and dungeon are not counted.

Thank you in advance.
