I am using the latest version of Pettracker. The Wanderer's Festival Hatchling is listed in the wrong place. It needs to be farther south on Turtle Beach. About coordinates 71,33.
Also, the Qiraji Guardling does not show at all on the map. It is a summer only pet, like snowy owl is in winter.
One final thing, two small bugs. 1) When I have battle pets that I have not captured showing in the objectives, once I capture one, it does not show that I've added it until I either /reload or leave the zone and come back. 2) If I log into a zone with non-captured pets showing, it will display them all as not captured even though I have. However, if I click on the pet journal, they instantly show as captured.
