I was just going through my achievements and I noticed I didn't have the Treasure Seeker one. I checked the old achievement page and I didn't have it before either. I went and doubled check and I have completed 3 maps.

Is this just a case of the achievement being added after the fact that I'd completed the maps(they were completely a long time ago) and the achievement not being one that is retroactive?

I believe you have to complete the Omen Islands Treasure Map for that one... I can't find the achievement though, but I think that's what it is!

OOPS no I'm wrong! Yeah, if you completed them before the achievement, you have to do it again. It's not retroactive :D

You have completed 3 maps so far!

You have access to the Omen Islands!

[edit] Mmkay. Probably shouldn't have sold all those map pieces I kept getting. Haha. :) Thanks.
