Guild Wars 2

So I have 14 of 15 hearts in Dieassa Plateau and I’ve explored the whole map. When I look on the wiki for a list of all hearts it only lists 14 of them. Is this a known issue/bug?

There are 15 Renown Hearts in Diessa Plateau – the wiki is missing the Renown Heart to Assist the Blood Legion vs. Separatists for Tiga Fierceblade in the Town of Nolan, which is close to the zone portal to The Black Citadel.
