Hello,
While running the End Time Dungeon on a lvl 120 character, the final dragon fight is bugged. Once the dragon is killed, combat doesn’t end and the NPC that takes you to the next dungeon does not appear. The mechanic works correctly on an lvl 100 character, but on the lvl 120 character it bugs every time.
I have tested and confirmed this twice over the daily reset and the bug happens every time on the lvl 120 character, while the lvl 100 character leaves combat and is able to go on the the next dungeon, Well of Eternity.
