I have 100% on every individual map including the WvW maps yet the list on the top left of my screen in the map says i still need 4 vistas and 11 Point of Interests and im stuck at 99% world completions. I revisited every map and all had 100 % so i dont understand whats going on.
Also had this issue. Was missing 11 POI and 4 Vistas. then i checked The Grove map and there it was.
