THE GROVE POI BUG
When you use the in game bug report tool, you will not get a response back from ArenaNet. That tool is just for reporting bugs directly to the development team. They do not send back individual responses for these reports.
If you are having an issue getting a specific POI, you might describe some details on what sort of issue you are having and almost always the people on the forums can help you find a way to reach it or find it.
If you enter the Sylvari Home Instance with your character of choice, and this PoI does not unlock, you may have a corrupted file. You can -repair your client by following the instructions found here: Top of Page – Support – Search (Repair).
If after a -repair, you enter the Home Instance, and it still does not unlock, you can contact the Tech Support CS Team and ask for assistance. Top of Page – Support – Submit a Request.
Good luck.
