Hero's Will Quest

Issue/Problem/Bug:
Can get the Mithril Wristband (for the last part of the quest) twice somehow.

Describe the problem. Be as specific as possible!:
I was walking around in Leafre when I saw this light bulb above Eurek's head. I accepted his quest, and got the Mithril Wristband. Seems normal so far right?
However, I've already received this wristband two days ago and completed the Hero's Will quest. Now I'm somehow back at the last part of the quest again.

Yes, the actual skill name and description for Hero's Will for Pirates is wrong as well. But as you can see it's Hero's Will in my skillbook, and I received the Mithril Wristband again, making the quest go back to the last part.


On my way to Aqua now to see what what happens when Carta gives me my will back, again. Will update soon.

Edit:
Was able to finish the quest again, and got the item Firm Hand. But as expected, when I tried using it, it said I couldn't use the skillbook.

Edit #2:
Went to El Nath to see Eurek again, and it didn't show the light bulb. But then I dropped the item Firm Hand, and the quest was available to me again. Seems like if you drop it, you can do it again. This makes sense, but it doesn't make sense that it becomes available when you actually use the item Firm Hand as well.

This is only happening on my Corsair, not on my Shadower. So most likely caused by the wrong Skill Name for Hero's Will for Pirates. If any other Corsair or Buccaneer can see if they get this quest again as well after obtaining Hero's Will, we could confim this. :p
