When I got back to the mission map to reenter F5 to accept the quest, I was not able to. I was doing quests on two characters at the time, and now I cannot complete the quest for Akia cave.
Here is the hero quest, I'm attempting to run through the chain again on my other account:
Edit: Apparently there is another quest chain given by a completely different NPC that unlocks the same exact F5 mode again. This is the most counter-intuitive, confusing bull-_- I've ever seen.
