No Kessex Hills Map rewards bugged heart
Perhaps, you might check your map against the map found here: http://wiki.guildwars2.com/wiki/Kessex_Hills
Good luck.
I have all 14/14 hearts completed, but one is bugged. There isn’t a missing one. But thank you.
Then, perhaps, the CS Team can assist you.
Good luck.
First you said you have 13/14 hearts, then you said 14/14.
Check the overhead map, or the mini-map, for a scout icon. Any scouts that show up on your map means you have not completed their heart.
If you read my first post I said that I have completed “all”, which means 14/14. I also said that map completion on map preview shows 13/14, hence my determining a heart bug. I also said that I went to each individual heart to confirm completion…ALL 14 and yes they are ALL completed and all heart vendors allow me to buy things from them.
