Hi!
Just wondering... I have the Hydro Yak egg in my nest at the moment (first image)... so I cleared the 120 levels of Battlegrounds to obtain it... but I then received the Caretaker quest to clear another 80 levels of Battlegrounds (second image)... andwon't be able to fulfil this one until more Battlegrounds levels open up... I guess it's kind of a bug?
(Also, I'm not sure if I uploaded the images correctly, so please bear with my technologically inept self. )
Little bugs aside, I love this game (and so does my son!), so please keep up the great work!
