Ok so it has happened to me TWICE while questing in Empyrea, I go inside the dungeon/boss battle and when i'm about to fight the last boss i port out to grab health orbs like a normal person does when they have no potions. Well, when you use Dungeon Recall the dungeon you're in resets and you have to do everything ALL OVER AGAIN and believe me, its annoying.
YES. This has happened to me several times, all with different dungeons. It makes me nervous having to port out of them because I fear I'll have to restart. I hope they fix this!
