There are 2 hearts in Wayfarer Foothills map that require the player to remove grawl symbols as part of these heart quests.
The problem is that the emblems don’t count towards the heart, even though they should.
I think the hearts are;
Fight the ice dragon’s corruption – and the emblem area is near the poi Heart of Corruption.
Disrupt Grawl worship – in the nearby cave.
Both these hearts have other ways to get exp, so I suspect not many (if any) have reported the problem. But it is strange how these emblems you can remove but don’t count to the heart.
