During the last boss, if you are trapped inside the aoe that's made by the "The mythril verge" by the time the final boss dies, you will forever be trapped inside the area, despite the fact it goes away when the battle concludes. This hinders me from exiting the dungeon. Luckily I got credit for the win but wanted to point this out incase this can potentially screw someone out of a win.

Location: The Sunken Temple of Qarn via duty finder, last area of the stage
